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-2023-0045:
    The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The     ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL     MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the     TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to     the prctl syscall. The patch that added the support for the conditional mitigation via prctl     (ib_prctl_set) dates back to the kernel 4.9.176.

    CVE-2023-0394:
    A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network     subcomponent in the Linux kernel. This flaw causes the system to crash.

    CVE-2023-1076:
    A flaw was found in the Linux Kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a     type confusion in their initialization function. While it will be often correct, as tuntap devices require     CAP_NET_ADMIN, it may not always be the case, e.g., a non-root user only having that capability. This     would make tun/tap sockets being incorrectly treated in filtering/routing decisions, possibly bypassing     network filters.

    CVE-2023-20938:
    In binder_transaction_buffer_release of binder.c, there is a possible use after free due to improper input     validation. This could lead to local escalation of privilege with no additional execution privileges     needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid     ID: A-257685302References: Upstream kernel

    CVE-2023-2513:
    A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the     extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system     crash or other undefined behaviors.

    CVE-2023-30456:
    An issue was discovered in arch/x86/kvm/vmx/nested.c in the Linux kernel before 6.2.8. nVMX on x86_64     lacks consistency checks for CR0 and CR4.

    CVE-2023-31436:
    qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write     because lmax can exceed QFQ_MIN_LMAX.

    CVE-2023-32269:
    An issue was discovered in the Linux kernel before 6.1.11. In net/netrom/af_netrom.c, there is a use-     after-free because accept is also allowed for a successfully connected AF_NETROM socket. However, in order     for an attacker to exploit this, the system must have netrom routing configured or the attacker must have     the CAP_NET_ADMIN capability.

    CVE-2023-35001:
    Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register     contents when CAP_NET_ADMIN is in any user or network namespace

    CVE-2023-4128:
    A use-after-free flaw was found in net/sched/cls_fw.c in classifiers (cls_fw, cls_u32, and cls_route) in     the Linux Kernel. This flaw allows a local attacker to perform a local privilege escalation due to     incorrect handling of the existing filter, leading to a kernel information leak issue.

    CVE-2022-0847:
    A flaw was found in the way the flags member of the new pipe buffer structure was lacking proper     initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus     contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache     backed by read only files and as such escalate their privileges on the system.

    CVE-2023-2269:
    A denial of service problem was found, due to a possible recursive locking scenario, resulting in a     deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-     component.
