CVE-2024-12086: Rsync: rsync server leaks arbitrary client files

MediumCVSS 6.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 28/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 1.7% (FIRST EPSS); higher than 78.6% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
Fixed version: azl3 rsync 3.2.7-1 on Azure Linux 3.0 3.4.1-1; azl3 rsync 3.4.1-1 on Azure Linux 3.0 3.4.1-1; cbl2 rsync 3.2.5-1 on CBL Mariner 2.0 3.4.1-1.

Low priority for now. Upgrade to azl3 rsync 3.2.7-1 on Azure Linux 3.0 3.4.1-1; azl3 rsync 3.4.1-1 on Azure Linux 3.0 3.4.1-1; cbl2 rsync 3.2.5-1 on CBL Mariner 2.0 3.4.1-1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
