CVE-2018-1160

84
FAUCET Score

CVE-2018-1160 is a critical out-of-bounds write vulnerability in Netatalk versions prior to 3.1.12, affecting products like Debian and Synology. This flaw allows a remote, unauthenticated attacker to achieve arbitrary code execution due to insufficient bounds checking on attacker-controlled data. With a CVSS score of 9.8 (Critical) and an EPSS score indicating high exploitability, it presents a significant risk. While not listed on CISA's KEV catalog, there are multiple public Proof-of-Concept exploits available on ExploitDB, though these are for authentication bypass rather than the described arbitrary code execution. The vulnerability has garnered notable community discussion and media coverage, including articles from BleepingComputer and SecurityWeek.
