The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:4076 advisory.

  - When importing a curve25519 private key in PKCS#8format with leading 0x00 bytes, it is possible to trigger     an out-of-bounds read in the Network Security Services (NSS) library. This could lead to information     disclosure. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.
    (CVE-2019-11719)

  - A vulnerability exists where it possible to force Network Security Services (NSS) to sign     CertificateVerify with PKCS#1 v1.5 signatures when those are the only ones advertised by server in     CertificateRequest in TLS 1.3. PKCS#1 v1.5 signatures should not be used for TLS 1.3 messages. This     vulnerability affects Firefox < 68. (CVE-2019-11727)

  - Improper refcounting of soft token session objects could cause a use-after-free and crash (likely limited     to a denial of service). This vulnerability affects Firefox < 71. (CVE-2019-11756)

  - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length     checks. In cases where the application calling the library did not perform a sanity check on the inputs it     could result in a crash due to a buffer overflow. (CVE-2019-17006)

  - After a HelloRetryRequest has been sent, the client may negotiate a lower protocol that TLS 1.3, resulting     in an invalid state transition in the TLS State Machine. If the client gets into this state, incoming     Application Data records will be ignored. This vulnerability affects Firefox < 72. (CVE-2019-17023)

  - When converting coordinates from projective to affine, the modular inversion was not performed in constant     time, resulting in a possible timing-based side channel attack. This vulnerability affects Firefox < 80     and Firefox for Android < 80. (CVE-2020-12400)

  - During ECDSA signature generation, padding applied in the nonce designed to ensure constant-time scalar     multiplication was removed, resulting in variable-time execution dependent on secret data. This     vulnerability affects Firefox < 80 and Firefox for Android < 80. (CVE-2020-12401)

  - During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean     Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform     electromagnetic-based side channel attacks to record traces leading to the recovery of the secret primes.
    *Note:* An unmodified Firefox browser does not generate RSA keys in normal operation and is not affected,     but products built on top of it might. This vulnerability affects Firefox < 78. (CVE-2020-12402)

  - A flaw was found in the way CHACHA20-POLY1305 was implemented in NSS in versions before 3.55. When using     multi-part Chacha20, it could cause out-of-bounds reads. This issue was fixed by explicitly disabling     multi-part ChaCha20 (which was not functioning correctly) and strictly enforcing tag length. The highest     threat from this vulnerability is to confidentiality and system availability. (CVE-2020-12403)

  - When performing EC scalar point multiplication, the wNAF point multiplication algorithm was used; which     leaked partial information about the nonce used during signature generation. Given an electro-magnetic     trace of a few signature generations, the private key could have been computed. This vulnerability affects     Firefox < 80 and Firefox for Android < 80. (CVE-2020-6829)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

    A vulnerability exists where it possible to force Network Security Services (NSS) to sign     CertificateVerify with PKCS#1 v1.5 signatures when those are the only ones advertised by server in     CertificateRequest in TLS 1.3. PKCS#1 v1.5 signatures should not be used for TLS 1.3 messages. This     vulnerability affects Firefox < 68. (CVE-2019-11727)

    A use-after-free flaw was found in Mozilla Network Security Services (NSS) related to PK11 session     handling. An attacker could use this flaw to execute arbitrary code with the permissions of the user     running the application compiled with NSS. (CVE-2019-11756)

    A vulnerability was discovered in nss where input text length was not checked when using certain     cryptographic primitives. This could lead to a heap-buffer overflow resulting in a crash and data leak.
    The highest threat is to confidentiality and integrity of data as well as system availability.
    (CVE-2019-17006)

    A protocol downgrade flaw was found in Network Security Services (NSS). After a HelloRetryRequest has been     sent, the client may negotiate a lower protocol than TLS 1.3, resulting in an invalid state transition in     the TLS State Machine. If the client gets into this state, incoming Application Data records will be     ignored. (CVE-2019-17023)

    A side-channel flaw was found in NSS, in the way P-384 and P-521 curves are used in the generation of EDSA     signatures, leaking partial information about the ECDSA nonce. Given a small number of ECDSA signatures,     this information can be used to steal the private key. The highest threat from this vulnerability is to     data confidentiality. (CVE-2020-12400)

    A flaw was found in nss. Using the EM side-channel, it is possible to extract the position of zero and     non-zero wNAF digits while nss-certutil tool performs scalar multiplication during the ECDSA signature     generation, leaking partial information about the ECDSA nonce. Given a small number of ECDSA signatures,     this information can be used to steal the private key. The highest threat from this vulnerability is to     data confidentiality. (CVE-2020-12401)

    A flaw was found in NSS, where it is vulnerable to RSA key generation cache timing side-channel attacks.
    An attacker with sufficient access to mount cache timing attacks during the RSA key generation process     could recover the private key. The highest threat to this flaw is to confidentiality. (CVE-2020-12402)

    A flaw was found in the way CHACHA20-POLY1305 was implemented in NSS. When using multi-part Chacha20, it     could cause out-of-bounds reads. This issue was fixed by explicitly disabling multi-part ChaCha20 (which     was not functioning correctly) and strictly enforcing tag length.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of AOS installed on the remote host is prior to 5.19.0.5. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.19.0.5 advisory.

  - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length     checks. In cases where the application calling the library did not perform a sanity check on the inputs it     could result in a crash due to a buffer overflow. (CVE-2019-17006)

  - Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3. (CVE-2019-5482)

  - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.
    When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may     contain files with permissions the attacker did not have or in paths he did not have access to. Extracting     those archives from a high-privilege user without carefully reviewing them may lead to the compromise of     the system. (CVE-2019-14866)

  - If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to     8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the     HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP     headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This     could lead to users seeing responses for unexpected resources. (CVE-2020-13943)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported     versions that are affected are 5.6.45 and prior, 5.7.27 and prior and 8.0.17 and prior. Easily exploitable     vulnerability allows low privileged attacker with network access via multiple protocols to compromise     MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang     or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2019-2974)

The version of Firefox installed on the remote Windows host is prior to 68.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-21 advisory.

  - Until explicitly accessed by script, <code>window.globalThis</code> is not enumerable and, as a result, is     not visible to code such as <code>Object.getOwnPropertyNames(window)</code>. Sites that deploy a     sandboxing that depends on enumerating and freezing access to the window object may miss this, allowing     their sandboxes to be bypassed. (CVE-2019-11716)

  - Necko can access a child on the wrong thread during UDP connections, resulting in a potentially     exploitable crash in some instances. (CVE-2019-11714)

  - As part of his winning Pwn2Own entry, Niklas Baumstark demonstrated a sandbox escape by installing a     malicious language pack and then opening a browser feature that used the compromised translation.
    (CVE-2019-9811)

  - When an inner window is reused, it does not consider the use of <code>document.domain</code> for cross-     origin protections. If pages on different subdomains ever cooperatively use <code>document.domain</code>,     then either page can abuse this to inject script into arbitrary pages on the other subdomain, even those     that did not use <code>document.domain</code> to relax their origin security. (CVE-2019-11711)

  - POST requests made by NPAPI plugins, such as Flash, that receive a status 308 redirect response can bypass     CORS requirements. This can allow an attacker to perform Cross-Site Request Forgery (CSRF) attacks.

  - nss: TLS 1.3 HelloRetryRequest downgrade request sets     client into invalid state (CVE-2019-17023)

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has nss packages installed that are affected by multiple vulnerabilities:

  - When importing a curve25519 private key in PKCS#8format with leading 0x00 bytes, it is possible to trigger     an out-of-bounds read in the Network Security Services (NSS) library. This could lead to information     disclosure. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.
    (CVE-2019-11719)

  - A vulnerability exists where it possible to force Network Security Services (NSS) to sign     CertificateVerify with PKCS#1 v1.5 signatures when those are the only ones advertised by server in     CertificateRequest in TLS 1.3. PKCS#1 v1.5 signatures should not be used for TLS 1.3 messages. This     vulnerability affects Firefox < 68. (CVE-2019-11727)

  - Improper refcounting of soft token session objects could cause a use-after-free and crash (likely limited     to a denial of service). This vulnerability affects Firefox < 71. (CVE-2019-11756)

  - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length     checks. In cases where the application calling the library did not perform a sanity check on the inputs it     could result in a crash due to a buffer overflow. (CVE-2019-17006)

  - After a HelloRetryRequest has been sent, the client may negotiate a lower protocol that TLS 1.3, resulting     in an invalid state transition in the TLS State Machine. If the client gets into this state, incoming     Application Data records will be ignored. This vulnerability affects Firefox < 72. (CVE-2019-17023)

  - When converting coordinates from projective to affine, the modular inversion was not performed in constant     time, resulting in a possible timing-based side channel attack. This vulnerability affects Firefox < 80     and Firefox for Android < 80. (CVE-2020-12400)

  - During ECDSA signature generation, padding applied in the nonce designed to ensure constant-time scalar     multiplication was removed, resulting in variable-time execution dependent on secret data. This     vulnerability affects Firefox < 80 and Firefox for Android < 80. (CVE-2020-12401)

  - During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean     Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform     electromagnetic-based side channel attacks to record traces leading to the recovery of the secret primes.
    *Note:* An unmodified Firefox browser does not generate RSA keys in normal operation and is not affected,     but products built on top of it might. This vulnerability affects Firefox < 78. (CVE-2020-12402)

  - A flaw was found in the way CHACHA20-POLY1305 was implemented in NSS in versions before 3.55. When using     multi-part Chacha20, it could cause out-of-bounds reads. This issue was fixed by explicitly disabling     multi-part ChaCha20 (which was not functioning correctly) and strictly enforcing tag length. The highest     threat from this vulnerability is to confidentiality and system availability. (CVE-2020-12403)

  - When performing EC scalar point multiplication, the wNAF point multiplication algorithm was used; which     leaked partial information about the nonce used during signature generation. Given an electro-magnetic     trace of a few signature generations, the private key could have been computed. This vulnerability affects     Firefox < 80 and Firefox for Android < 80. (CVE-2020-6829)
