Several vulnerabilities were discovered in salt, a powerful remote execution manager, which could result in retrieve of user tokens from the salt master, execution of arbitrary commands on salt minions, arbitrary directory access to authenticated users or arbitrary code execution on salt-api hosts.

The version of AOS installed on the remote host is prior to 6.0.2.5. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.0.2.5 advisory.

  - xpointer.c in libxml2 before 2.9.5 (as used in Apple iOS before 10, OS X before 10.12, tvOS before 10, and     watchOS before 3, and other products) does not forbid namespace nodes in XPointer ranges, which allows     remote attackers to execute arbitrary code or cause a denial of service (use-after-free and memory     corruption) via a crafted XML document. (CVE-2016-4658)

  - NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow     when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures     encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted. Applications using NSS for     certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how     they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However, email clients and     PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and     Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1.
    (CVE-2021-43527)

  - An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass     RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users     with the ability to start and control a VM to read/write random pages of memory and can result in local     privilege escalation. (CVE-2021-22543)

  - A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when     processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested     guest (L2). Due to improper validation of the int_ctl field, this issue could allow a malicious L1 to     enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2 guest     would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak     of sensitive data or potential guest-to-host escape. This flaw affects Linux kernel versions prior to     5.14-rc7. (CVE-2021-3653)

  - A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when     processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested     guest (L2). Due to improper validation of the virt_ext field, this issue could allow a malicious L1 to     disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the     L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire     system, leak of sensitive data or potential guest-to-host escape. (CVE-2021-3656)

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 6.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.1 advisory.

  - xpointer.c in libxml2 before 2.9.5 (as used in Apple iOS before 10, OS X before 10.12, tvOS before 10, and     watchOS before 3, and other products) does not forbid namespace nodes in XPointer ranges, which allows     remote attackers to execute arbitrary code or cause a denial of service (use-after-free and memory     corruption) via a crafted XML document.

This vulnerability affects NSS < 3.73 and NSS < 3.68.1.
    (CVE-2021-43527)

  - Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow     unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.
    (CVE-2017-5715)

  - Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized     disclosure of information to an attacker with local user access via a side-channel analysis.
    (CVE-2017-5753)

  - Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow     unauthorized disclosure of information to an attacker with local user access via a side-channel analysis     of the data cache. (CVE-2017-5754)

This update was imported from the SUSE:SLE-15-SP1:Update update project.

The version of AOS installed on the remote host is prior to 6.1.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.1.1 advisory.

  - JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write     access to the Log4j configuration. The attacker can provide TopicBindingName and     TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result     in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2     when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of     life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the     previous versions. (CVE-2021-4104)

  - It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-     default configurations. This could allows attackers with control over Thread Context Map (MDC) input data     when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for     example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input     data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some     environments and local code execution in all environments. Log4j 2.16.0 (Java 8) and 2.12.2 (Java 7) fix     this issue by removing support for message lookup patterns and disabling JNDI functionality by default.
    (CVE-2021-45046)

  - Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI     features used in configuration, log messages, and parameters do not protect against attacker controlled     LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters     can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From     log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3,     and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to     log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects.
    (CVE-2021-44228)

  - xpointer.c in libxml2 before 2.9.5 (as used in Apple iOS before 10, OS X before 10.12, tvOS before 10, and     watchOS before 3, and other products) does not forbid namespace nodes in XPointer ranges, which allows     remote attackers to execute arbitrary code or cause a denial of service (use-after-free and memory     corruption) via a crafted XML document. (CVE-2016-4658)

  - NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow     when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures     encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted. Applications using NSS for     certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how     they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However, email clients and     PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and     Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1.
    (CVE-2021-43527)

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

According to its self-reported version number, the instance of SaltStack hosted on the remote server is prior to 2019.2.4, 3000.x prior to 3000.2. It is, therefore, affected by multiple vulnerabilities:

  - An authentication bypass vulnerabilities exists in the ClearFuncs class due to improper validation of     method calls. An unauthenticated, remote attacker can exploit this by accessing exposed methods to trigger     minions to run arbitrary commands as root, or to retrieve the root key to authenticate commands from the     local root user on the master server. (CVE-2020-11651)

  - A directory traversal vulnerabilities exists in the ClearFuncs class due to improper path sanitization. An     authenticated, remote attacker can exploit this by accessing the exposed get_token() method which allows     the insertion of double periods in the filename parameter to read files outside of the intended directory.
    The only restriction is that the file has to be deserializable by salt.payload.Serial.loads().
    (CVE-2020-11652)

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:2106-1 advisory.

  - Directory Traversal vulnerability in salt-api in SaltStack Salt before 2017.7.8 and 2018.3.x before     2018.3.3 allows remote attackers to determine which files exist on the server. (CVE-2018-15750)

  - SaltStack Salt before 2017.7.8 and 2018.3.x before 2018.3.3 allow remote attackers to bypass     authentication and execute arbitrary commands via salt-api(netapi). (CVE-2018-15751)

  - An issue was discovered in SaltStack Salt before 2019.2.4 and 3000 before 3000.2. The salt-master process     ClearFuncs class does not properly validate method calls. This allows a remote user to access some methods     without authentication. These methods can be used to retrieve user tokens from the salt master and/or run     arbitrary commands on salt minions. (CVE-2020-11651)

  - An issue was discovered in SaltStack Salt before 2019.2.4 and 3000 before 3000.2. The salt-master process     ClearFuncs class allows access to some methods that improperly sanitize paths. These methods allow     arbitrary directory access to authenticated users. (CVE-2020-11652)

  - In SaltStack Salt through 3002, salt-netapi improperly validates eauth credentials and tokens. A user can     bypass authentication and invoke Salt SSH. (CVE-2020-25592)

  - A Incorrect Implementation of Authentication Algorithm vulnerability in of SUSE SUSE Linux Enterprise     Server 15 SP 3; openSUSE Tumbleweed allows local attackers to execute arbitrary code via salt without the     need to specify valid credentials. This issue affects: SUSE SUSE Linux Enterprise Server 15 SP 3 salt     versions prior to 3002.2-3. openSUSE Tumbleweed salt version 3002.2-2.1 and prior versions.
    (CVE-2021-25315)

  - In SaltStack Salt 2016.9 through 3002.6, a command injection vulnerability exists in the snapper module     that allows for local privilege escalation on a minion. The attack requires that a file is created with a     pathname that is backed up by snapper, and that the master calls the snapper.diff function (which executes     popen unsafely). (CVE-2021-31607)

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

The version of SaltStack installed on the remote server is affected by an authentication bypass vulnerability in the ClearFuncs class due to improper validation of method calls. An unauthenticated, remote attacker can exploit this by accessing exposed methods to trigger minions to run arbitrary commands as root, or to retrieve the root key to authenticate commands from the local root user on the master server.

Several vulnerabilities were discovered in package salt, a configuration management and infrastructure automation software.

CVE-2020-11651

The salt-master process ClearFuncs class does not properly validate method calls. This allows a remote user to access some methods without authentication. These methods can be used to retrieve user tokens from the salt master and/or run arbitrary commands on salt minions.

CVE-2020-11652

The salt-master process ClearFuncs class allows access to some methods that improperly sanitize paths. These methods allow arbitrary directory access to authenticated users.

For Debian 8 'Jessie', these problems have been fixed in version 2014.1.13+ds-3+deb8u1.

We recommend that you upgrade your salt packages.
