CVSS: 10.0EPSS: 2%CPEs: 16EXPL: 2CVE-2024-12084 – Rsync: heap buffer overflow in rsync due to improper checksum length handling
https://notcve.org/view.php?id=CVE-2024-12084
15 Jan 2025 — A heap-based buffer overflow flaw was found in the rsync daemon. This issue is due to improper handling of attacker-controlled checksum lengths (s2length) in the code. When MAX_DIGEST_LEN exceeds the fixed SUM_LENGTH (16 bytes), an attacker can write out of bounds in the sum2 buffer. Simon Scannell, Pedro Gallegos, and Jasiel Spelman discovered that rsync did not properly handle checksum lengths. An attacker could use this issue to execute arbitrary code. • https://github.com/themirze/cve-2024-12084 • CWE-122: Heap-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2024-12087
14 Jan 2025 — 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 m... • https://access.redhat.com/security/cve/CVE-2024-12087 • CWE-35: Path Traversal: '.../ •

https://notcve.org/view.php?id=CVE-2024-12088
14 Jan 2025 — 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. A flaw was found in rsync. When using the `--safe-links` option, the rsync client fails to properly verify if a symbolic link destination sent from the server contains another symbolic link within it. • https://access.redhat.com/security/cve/CVE-2024-12088 • CWE-35: Path Traversal: '.../ •

https://notcve.org/view.php?id=CVE-2024-12086
14 Jan 2025 — 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 ba... • https://access.redhat.com/security/cve/CVE-2024-12086 • CWE-390: Detection of Error Condition Without Action •

02 Aug 2022 — An issue was discovered in rsync before 3.2.5 that allows malicious remote servers to write arbitrary files inside the directories of connecting peers. The server chooses which files/directories are sent to the client. However, the rsync client performs insufficient validation of file names. A malicious rsync server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the rsync client target directory and subdirectories (for example, overwrite the .ssh/authorized_keys file).

27 May 2021 — A flaw was found in rsync in versions since 3.2.0pre1. Rsync improperly validates certificate with host mismatch vulnerability. A remote, unauthenticated attacker could exploit the flaw by performing a man-in-the-middle attack using a valid certificate for another hostname which could compromise confidentiality and integrity of data transmitted using rsync-ssl. The highest threat from this vulnerability is to data confidentiality and integrity. This flaw affects rsync versions before 3.2.4. • https://bugzilla.redhat.com/show_bug.cgi?id=1875549 • CWE-297: Improper Validation of Certificate with Host Mismatch •
