It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-306 advisory.

    Issue summary: The AES-SIV cipher implementation contains a bug that causesit to ignore empty associated     data entries which are unauthenticated asa consequence.

    Impact summary: Applications that use the AES-SIV algorithm and want toauthenticate empty data entries as     associated data can be mislead by removingadding or reordering such empty entries as these are ignored by     the OpenSSLimplementation. We are currently unaware of any such applications.

    The AES-SIV algorithm allows for authentication of multiple associateddata entries along with the     encryption. To authenticate empty data theapplication has to call EVP_EncryptUpdate() (or     EVP_CipherUpdate()) withNULL pointer as the output buffer and 0 as the input buffer length.The AES-SIV     implementation in OpenSSL just returns success for such a callinstead of performing the associated data     authentication operation.The empty data thus will not be authenticated.

    As this issue does not affect non-empty associated data authentication andwe expect it to be rare for an     application to use empty associated dataentries this is qualified as Low severity issue. (CVE-2023-2975)

    Issue summary: Checking excessively long DH keys or parameters may be very slow.

    Impact summary: Applications that use the functions DH_check(), DH_check_ex()or EVP_PKEY_param_check() to     check a DH key or DH parameters may experience longdelays. Where the key or parameters that are being     checked have been obtainedfrom an untrusted source this may lead to a Denial of Service.

    The function DH_check() performs various checks on DH parameters. One of thosechecks confirms that the     modulus ('p' parameter) is not too large. Trying to usea very large modulus is slow and OpenSSL will not     normally use a modulus whichis over 10,000 bits in length.

    However the DH_check() function checks numerous aspects of the key or parametersthat have been supplied.
    Some of those checks use the supplied modulus valueeven if it has already been found to be too large.

    An application that calls DH_check() and supplies a key or parameters obtainedfrom an untrusted source     could be vulernable to a Denial of Service attack.

    The function DH_check() is itself called by a number of other OpenSSL functions.An application calling any     of those other functions may similarly be affected.The other functions affected by this are DH_check_ex()     andEVP_PKEY_param_check().

    Also vulnerable are the OpenSSL dhparam and pkeyparam command line applicationswhen using the '-check'     option.

    The OpenSSL SSL/TLS implementation is not affected by this issue.The OpenSSL 3.0 and 3.1 FIPS providers     are not affected by this issue. (CVE-2023-3446)

    Issue summary: Checking excessively long DH keys or parameters may be very slow.

    The function DH_check() performs various checks on DH parameters. After fixingCVE-2023-3446 it was     discovered that a large q parameter value can also triggeran overly long computation during some of these     checks. A correct q value,if present, cannot be larger than the modulus p parameter, thus it isunnecessary     to perform these checks if q is larger than p.

  - Issue summary: A bug has been identified in the processing of key and initialisation vector (IV) lengths.
    This can lead to potential truncation or overruns during the initialisation of some symmetric ciphers.
    Impact summary: A truncation in the IV can result in non-uniqueness, which could result in loss of     confidentiality for some cipher modes. When calling EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2() or     EVP_CipherInit_ex2() the provided OSSL_PARAM array is processed after the key and IV have been     established. Any alterations to the key length, via the keylen parameter or the IV length, via the     ivlen parameter, within the OSSL_PARAM array will not take effect as intended, potentially causing     truncation or overreading of these values. The following ciphers and cipher modes are impacted: RC2, RC4,     RC5, CCM, GCM and OCB. For the CCM, GCM and OCB cipher modes, truncation of the IV can result in loss of     confidentiality. For example, when following NIST's SP 800-38D section 8.2.1 guidance for constructing a     deterministic IV for AES in GCM mode, truncation of the counter portion could lead to IV reuse. Both     truncations and overruns of the key and overruns of the IV will produce incorrect results and could, in     some cases, trigger a memory exception. However, these issues are not currently assessed as security     critical. Changing the key and/or IV lengths is not considered to be a common operation and the vulnerable     API was recently introduced. Furthermore it is likely that application developers will have spotted this     problem during testing since decryption would fail unless both peers in the communication were similarly     vulnerable. For these reasons we expect the probability of an application being vulnerable to this to be     quite low. However if an application is vulnerable then this issue is considered very serious. For these     reasons we have assessed this issue as Moderate severity overall. The OpenSSL SSL/TLS implementation is     not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers are not affected by this because the     issue lies outside of the FIPS provider boundary. OpenSSL 3.1 and 3.0 are vulnerable to this issue.
    (CVE-2023-5363)

  - Issue summary: Generating excessively long X9.42 DH keys or checking excessively long X9.42 DH keys or     parameters may be very slow. Impact summary: Applications that use the functions DH_generate_key() to     generate an X9.42 DH key may experience long delays. Likewise, applications that use DH_check_pub_key(),     DH_check_pub_key_ex() or EVP_PKEY_public_check() to check an X9.42 DH key or X9.42 DH parameters may     experience long delays. Where the key or parameters that are being checked have been obtained from an     untrusted source this may lead to a Denial of Service. While DH_check() performs all the necessary checks     (as of CVE-2023-3817), DH_check_pub_key() doesn't make any of these checks, and is therefore vulnerable     for excessively large P and Q parameters. Likewise, while DH_generate_key() performs a check for an     excessively large P, it doesn't check for an excessively large Q. An application that calls     DH_generate_key() or DH_check_pub_key() and supplies a key or parameters obtained from an untrusted source     could be vulnerable to a Denial of Service attack. DH_generate_key() and DH_check_pub_key() are also     called by a number of other OpenSSL functions. An application calling any of those other functions may     similarly be affected. The other functions affected by this are DH_check_pub_key_ex(),     EVP_PKEY_public_check(), and EVP_PKEY_generate(). Also vulnerable are the OpenSSL pkey command line     application when using the -pubcheck option, as well as the OpenSSL genpkey command line application.
    The OpenSSL SSL/TLS implementation is not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers     are not affected by this issue. (CVE-2023-5678)

The version of Siemens SINEC NMS installed on the remote host is prior to 2.0.1.0. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA-943925 advisory.

  - coreruleset (aka OWASP ModSecurity Core Rule Set) through 3.3.4 does not detect multiple Content-Type     request headers on some platforms. This might allow attackers to bypass a WAF with a crafted payload,     aka Content-Type confusion between the WAF and the backend application. This occurs when the web     application relies on only the last Content-Type header. Other platforms may reject the additional     Content-Type header or merge conflicting headers, leading to detection as a malformed header.
    (CVE-2023-38199)

  - Some mod_proxy configurations on Apache HTTP Server versions 2.4.0 through 2.4.55 allow a HTTP Request     Smuggling attack. Configurations are affected when mod_proxy is enabled along with some form of     RewriteRule or ProxyPassMatch in which a non-specific pattern matches some portion of the user-supplied     request-target (URL) data and is then re-inserted into the proxied request-target using variable     substitution. For example, something like: RewriteEngine on RewriteRule ^/here/(.*)     http://example.com:8080/elsewhere?$1; [P] ProxyPassReverse /here/ http://example.com:8080/ Request     splitting/smuggling could result in bypass of access controls in the proxy server, proxying unintended     URLs to existing origin servers, and cache poisoning. Users are recommended to update to at least version     2.4.56 of Apache HTTP Server. (CVE-2023-25690)

  - The use of `Module._load()` can bypass the policy mechanism and require modules outside of the policy.json     definition for a given module. This vulnerability affects all users using the experimental policy     mechanism in all active release lines: 16.x, 18.x and, 20.x. Please note that at the time this CVE was     issued, the policy is an experimental feature of Node.js. (CVE-2023-32002)
