The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-2899 advisory.

    The Qualys Research Labs discovered a local privilege escalation in PolicyKit's pkexec. Details can be     found in the Qualys advisory at https://www.qualys.com/2022/01/25/cve-2021-4034/pwnkit.txt For Debian 9     stretch, this problem has been fixed in version 0.105-18+deb9u2. We recommend that you upgrade your     policykit-1 packages. For the detailed security status of policykit-1 please refer to its security tracker     page at: https://security-tracker.debian.org/tracker/policykit-1 Further information about Debian LTS     security advisories, how to apply these updates to your system and frequently asked questions can be found     at: https://wiki.debian.org/LTS

The remote OracleVM system is missing necessary patches to address security updates:

  - A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is     a setuid tool designed to allow unprivileged users to run commands as privileged users according     predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly     and ends trying to execute environment variables as commands. An attacker can leverage this by crafting     environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully     executed the attack can cause a local privilege escalation given unprivileged users administrative rights     on the target machine. (CVE-2021-4034)

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

According to the versions of the polkit packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

According to the versions of the polkit packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - There is a flaw in polkit which can allow an unprivileged user to cause polkit to crash, due to process     file descriptor exhaustion. The highest threat from this vulnerability is to availability. NOTE: Polkit     process outage duration is tied to the failing process being reaped and a new one being spawned     (CVE-2021-4115)

The version of AOS installed on the remote host is prior to 5.20.3.5. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.20.3.5 advisory.

  - CVE-2020-9493 identified a deserialization issue that was present in Apache Chainsaw. Prior to Chainsaw     V2.0 Chainsaw was a component of Apache Log4j 1.2.x where the same issue exists. (CVE-2022-23307)

  - By design, the JDBCAppender in Log4j 1.2.x accepts an SQL statement as a configuration parameter where the     values to be inserted are converters from PatternLayout. The message converter, %m, is likely to always be     included. This allows attackers to manipulate the SQL by entering crafted strings into input fields or     headers of an application that are logged allowing unintended SQL queries to be executed. Note this issue     only affects Log4j 1.x when specifically configured to use the JDBCAppender, which is not the default.
    Beginning in version 2.0-beta8, the JDBCAppender was re-introduced with proper support for parameterized     SQL queries and further customization over the columns written to in logs. 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-2022-23305)

  - AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS     extended attributes or tmpfs ACLs), because of a heap-based buffer overflow. (CVE-2021-45417)

  - Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data     which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when     listening to untrusted network traffic for log data. This affects Log4j versions up to 1.2 up to 1.2.17.
    (CVE-2019-17571)

  - Improper validation of certificate with host mismatch in Apache Log4j SMTP appender. This could allow an     SMTPS connection to be intercepted by a man-in-the-middle attack which could leak any log messages sent     through that appender. Fixed in Apache Log4j 2.12.3 and 2.13.1 (CVE-2020-9488)

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

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

  - A flaw was found in polkit before version 0.116. The implementation of the     polkit_backend_interactive_authority_check_authorization function in polkitd allows to test for     authentication and trigger authentication of unrelated processes owned by other users. This may result in     a local DoS and information disclosure. (CVE-2018-1116)

  - A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is     a setuid tool designed to allow unprivileged users to run commands as privileged users according     predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly     and ends trying to execute environment variables as commands. An attacker can leverage this by crafting     environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully     executed the attack can cause a local privilege escalation given unprivileged users administrative rights     on the target machine. (CVE-2021-4034)

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2022:0004 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2019-6133:
    In PolicyKit (aka polkit) 0.115, the start time protection mechanism can be bypassed because fork() is     not atomic, and therefore authorization decisions are improperly cached. This is related to lack of uid     checking in polkitbackend/polkitbackendinteractiveauthority.c.
