The version of rsync installed on the remote host is prior to 3.1.2-11. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2025-2731 advisory.

    A flaw was found in the rsync daemon which could be triggered when rsync compares file checksums. This     flaw allows an attacker to manipulate the checksum length (s2length) to cause a comparison between a     checksum and uninitialized memory and leak one byte of uninitialized stack data at a time.
    (CVE-2024-12085)

    A flaw was found in rsync. It could allow a server to enumerate the contents of an arbitrary file from the     client's machine. This issue occurs when files are being copied from a client to a server. During this     process, the rsync server will send checksums of local data to the client to compare with in order to     determine what data needs to be sent to the server. By sending specially constructed checksum values for     arbitrary files, an attacker may be able to reconstruct the data of those files byte-by-byte based on the     responses from the client. (CVE-2024-12086)

    A path traversal vulnerability exists in rsync. It stems from behavior enabled by the `--inc-recursive`     option, a default-enabled option for many client options and can be enabled by the server even if not     explicitly enabled by the client. When using the `--inc-recursive` option, a lack of proper symlink     verification coupled with deduplication checks occurring on a per-file-list basis could allow a server to     write files outside of the client's intended destination directory. A malicious server could write     malicious files to arbitrary locations named after valid directories/paths on the client. (CVE-2024-12087)

    A flaw was found in rsync. When using the `--safe-links` option, rsync fails to properly verify if a     symbolic link destination contains another symbolic link within it. This results in a path traversal     vulnerability, which may lead to arbitrary file write outside the desired directory. (CVE-2024-12088)

    A flaw was found in rsync. This vulnerability arises from a race condition during rsync's handling of     symbolic links. Rsync's default behavior when encountering symbolic links is to skip them. If an attacker     replaced a regular file with a symbolic link at the right time, it was possible to bypass the default     behavior and traverse symbolic links. Depending on the privileges of the rsync process, an attacker could     leak sensitive information, potentially leading to privilege escalation. (CVE-2024-12747)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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