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 AOS installed on the remote host is prior to 5.11.2.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.11.2.1 advisory.

  - In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain policy     blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user     ID. For example, this allows bypass of !root configuration, and USER= logging, for a sudo -u     \#$((0xffffffff)) command. (CVE-2019-14287)

  - A flaw was found in the Linux kernel's NFS implementation, all versions 3.x and all versions 4.x up to     4.20. An attacker, who is able to mount an exported NFS filesystem, is able to trigger a null pointer     dereference by using an invalid NFS sequence. This can panic the machine and deny access to the NFS     server. Any outstanding disk writes to the NFS server will be lost. (CVE-2018-16871)

  - A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network     namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-     free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system     panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. (CVE-2018-16884)

  - Insufficient input validation in Kernel Mode Driver in Intel(R) i915 Graphics for Linux before version 5.0     may allow an authenticated user to potentially enable escalation of privilege via local access.
    (CVE-2019-11085)

  - An issue was discovered in the Linux kernel before 5.0.4. There is a use-after-free upon attempted read     access to /proc/ioports after the ipmi_si module is removed, related to drivers/char/ipmi/ipmi_si_intf.c,     drivers/char/ipmi/ipmi_si_mem_io.c, and drivers/char/ipmi/ipmi_si_port_io.c. (CVE-2019-11811)

This     vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service     which supplies data to the APIs. (CVE-2019-2989)

  - Vulnerability in the Java SE product of Oracle Java SE (component: Javadoc). Supported versions that are     affected are Java SE: 7u231, 8u221, 11.0.4 and 13. Difficult to exploit vulnerability allows     unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful     attacks require human interaction from a person other than the attacker and while the vulnerability is in     Java SE, attacks may significantly impact additional products. Successful attacks of this vulnerability     can result in unauthorized update, insert or delete access to some of Java SE accessible data as well as     unauthorized read access to a subset of Java SE accessible data. Note: This vulnerability applies to Java     deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets     (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the     Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers,     that load and run only trusted code (e.g., code installed by an administrator). (CVE-2019-2999)

  - A denial of service vulnerability was found in rsyslog in the imptcp module. An attacker could send a     specially crafted message to the imptcp socket, which would cause rsyslog to crash. Versions before 8.27.0     are vulnerable. (CVE-2018-16881)

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

  - Rsyslog is a rocket-fast system for log processing. Modules for TCP syslog reception have a potential heap     buffer overflow when octet-counted framing is used. This can result in a segfault or some other     malfunction. As of our understanding, this vulnerability can not be used for remote code execution. But     there may still be a slight chance for experts to do that. The bug occurs when the octet count is read.
    While there is a check for the maximum number of octets, digits are written to a heap buffer even when the     octet count is over the maximum, This can be used to overrun the memory buffer. However, once the sequence     of digits stop, no additional characters can be added to the buffer. In our opinion, this makes remote     exploits impossible or at least highly complex. Octet-counted framing is one of two potential framing     modes. It is relatively uncommon, but enabled by default on receivers. Modules `imtcp`, `imptcp`,     `imgssapi`, and `imhttp` are used for regular syslog message reception. It is best practice not to     directly expose them to the public. When this practice is followed, the risk is considerably lower. Module     `imdiag` is a diagnostics module primarily intended for testbench runs. We do not expect it to be present     on any production installation. Octet-counted framing is not very common. Usually, it needs to be     specifically enabled at senders. If users do not need it, they can turn it off for the most important     modules. This will mitigate the vulnerability. (CVE-2022-24903)
