CVE-2024-12085: Rsync: info leak via uninitialized stack contents
Noroxi assessment
Priority: Monitor (action score 33/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 8.6% (FIRST EPSS); higher than 95.1% 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. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- 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 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.
