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.

The version of rsync installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-12087 advisory.

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.

    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)

    CVE-2024-12084

        Simon Scannell, Pedro Gallegos and Jasiel Spelman discovered a         heap-based buffer overflow vulnerability due to improper handling of         attacker-controlled checksum lengths. A remote attacker can take         advantage of this flaw for code execution.

    CVE-2024-12085

        Simon Scannell, Pedro Gallegos and Jasiel Spelman reported a flaw in         the way rsync compares file checksums, allowing a remote attacker to         trigger an information leak.

    CVE-2024-12086

        Simon Scannell, Pedro Gallegos and Jasiel Spelman discovered a flaw         which would result in a server leaking contents of an arbitrary file         from the client's machine.

    CVE-2024-12087

        Simon Scannell, Pedro Gallegos and Jasiel Spelman reported a path         traversal vulnerability in the rsync daemon affecting the
        --inc-recursive option, which could allow a server to write files         outside of the client's intended destination directory.

    CVE-2024-12088

        Simon Scannell, Pedro Gallegos and Jasiel Spelman reported that when         using the --safe-links option, rsync fails to properly verify if a         symbolic link destination contains another symbolic link with it,         resulting in path traversal and arbitrary file write outside of the         desired directory.

    CVE-2024-12747

        Aleksei Gorban loqpa discovered a race condition when handling         symbolic links resulting in an information leak which may enable         escalation of privileges.

    For the stable distribution (bookworm), these problems have been fixed in     version 3.2.7-1+deb12u2.
