The remote Alibaba Cloud Linux 3 host has packages installed that are affected by a vulnerability as referenced in the ALINUX3-SA-2023:0108 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2023-26604:
    systemd before 247 does not adequately block local privilege escalation for some Sudo configurations,     e.g., plausible sudoers files in which the systemctl status command may be executed. Specifically,     systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This     presents a substantial security risk when running systemctl from Sudo, because less executes as root when     the terminal size is too small to show the complete systemctl output.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

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 AHV installed on the remote host is prior to 20230302.102005. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.1011 advisory.

  - Error handling in the SSH protocol in (1) SSH Tectia Client and Server and Connector 4.0 through 4.4.11,     5.0 through 5.2.4, and 5.3 through 5.3.8; Client and Server and ConnectSecure 6.0 through 6.0.4; Server     for Linux on IBM System z 6.0.4; Server for IBM z/OS 5.5.1 and earlier, 6.0.0, and 6.0.1; and Client 4.0-J     through 4.3.3-J and 4.0-K through 4.3.10-K; and (2) OpenSSH 4.7p1 and possibly other versions, when using     a block cipher algorithm in Cipher Block Chaining (CBC) mode, makes it easier for remote attackers to     recover certain plaintext data from an arbitrary block of ciphertext in an SSH session via unknown     vectors. (CVE-2008-5161)

  - The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path,     leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in     /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an     incomplete fix for CVE-2016-10009. (CVE-2023-38408)

  - A NULL pointer dereference was found In libssh during re-keying with algorithm guessing. This issue may     allow an authenticated client to cause a denial of service. (CVE-2023-1667)

  - A vulnerability was found in libssh, where the authentication check of the connecting client can be     bypassed in the`pki_verify_data_signature` function in memory allocation problems. This issue may happen     if there is insufficient memory or the memory usage is limited. The problem is caused by the return value     `rc,` which is initialized to SSH_ERROR and later rewritten to save the return value of the function call     `pki_key_check_hash_compatible.` The value of the variable is not changed between this point and the     cryptographic verification. Therefore any error between them calls `goto error` returning SSH_OK.
    (CVE-2023-2283)

  - Every `named` instance configured to run as a recursive resolver maintains a cache database holding the     responses to the queries it has recently sent to authoritative servers. The size limit for that cache     database can be configured using the `max-cache-size` statement in the configuration file; it defaults to     90% of the total amount of memory available on the host. When the size of the cache reaches 7/8 of the     configured limit, a cache-cleaning algorithm starts to remove expired and/or least-recently used RRsets     from the cache, to keep memory use below the configured limit. It has been discovered that the     effectiveness of the cache-cleaning algorithm used in `named` can be severely diminished by querying the     resolver for specific RRsets in a certain order, effectively allowing the configured `max-cache-size`     limit to be significantly exceeded. This issue affects BIND 9 versions 9.11.0 through 9.16.41, 9.18.0     through 9.18.15, 9.19.0 through 9.19.13, 9.11.3-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1.
    (CVE-2023-2828)

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

  - systemd before 247 does not adequately block local privilege escalation for some Sudo configurations,     e.g., plausible sudoers files in which the 'systemctl status' command may be executed. Specifically,     systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This     presents a substantial security risk when running systemctl from Sudo, because less executes as root when     the terminal size is too small to show the complete systemctl output. (CVE-2023-26604)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2023:3837 advisory.

    The systemd packages contain systemd, a system and service manager for Linux, compatible with the SysV and     LSB init scripts. It provides aggressive parallelism capabilities, uses socket and D-Bus activation for     starting services, offers on-demand starting of daemons, and keeps track of processes using Linux cgroups.
    In addition, it supports snapshotting and restoring of the system state, maintains mount and automount     points, and implements an elaborate transactional dependency-based service control logic. It can also work     as a drop-in replacement for sysvinit.

    Security Fix(es):

    * systemd: privilege escalation via the less pager (CVE-2023-26604)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

    Bug Fix(es):

    * systemd-pstore crashes when attempting to move standalone files out of /sys/fs/pstore (BZ#2190153)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - systemd before 247 does not adequately block local privilege escalation for some Sudo configurations,     e.g., plausible sudoers files in which the systemctl status command may be executed. Specifically,     systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This     presents a substantial security risk when running systemctl from Sudo, because less executes as root when     the terminal size is too small to show the complete systemctl output. (CVE-2023-26604)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2023:1622-1 advisory.

  - systemd before 247 does not adequately block local privilege escalation for some Sudo configurations,     e.g., plausible sudoers files in which the systemctl status command may be executed. Specifically,     systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program.

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

The remote NewStart CGSL host, running version MAIN 6.02, has systemd packages installed that are affected by multiple vulnerabilities:

  - A use-after-free vulnerability was found in systemd. This issue occurs due to the on_stream_io() function     and dns_stream_complete() function in 'resolved-dns-stream.c' not incrementing the reference counting for     the DnsStream object. Therefore, other functions and callbacks called can dereference the DNSStream     object, causing the use-after-free when the reference is still used later. (CVE-2022-2526)

  - A vulnerability was found in the systemd package. The systemd package does not adequately block local     privilege escalation for some Sudo configurations, for example, plausible sudoers files, in which the     systemctl status command may be executed. Specifically, systemd does not set LESSSECURE to 1, and thus     other programs may be launched from the less program. This issue presents a substantial security risk when     running systemctl from Sudo because less executes as root when the terminal size is too small to show the     complete systemctl output. (CVE-2023-26604)

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:02019-1 advisory.

    - CVE-2025-4598: Race condition that allows a local attacker to crash a SUID program and gain read access     to the resulting core dump (bsc#1243935).
    - CVE-2023-26604: Privilege escalation via the less pager (bsc#1208958).
    - CVE-2022-4415: systemd-coredump was not respecting fs.suid_dumpable kernel setting (bsc#1205000).

    Other bugfixes:

    - clarify passno and noauto combination in /etc/fstab (bsc#1211725)
    - handle -EINTR return from bus_poll() (bsc#1215241)
    - /usr/ should never be unmounted regardless of HAVE_SPLIT_USR or not (bsc#1211576)

The version of AHV installed on the remote host is prior to 20230302.102005. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.207 advisory.

  - In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in     xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).
    (CVE-2021-45960)

  - The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path,     leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in     /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an     incomplete fix for CVE-2016-10009. (CVE-2023-38408)

  - An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the     attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content     to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing     filenames with two or more newlines where selected content and the target file names are embedded in     crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write     arbitrary files on the system. (CVE-2022-1271)

  - http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5     allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR     and LF control characters in the first argument of HTTPConnection.request. (CVE-2020-26116)

  - urllib3 before 1.25.9 allows CRLF injection if the attacker controls the HTTP request method, as     demonstrated by inserting CR and LF control characters in the first argument of putrequest(). NOTE: this     is similar to CVE-2020-26116. (CVE-2020-26137)
