CVE-2023-30187 is a critical out-of-bounds memory access vulnerability affecting ONLYOFFICE DocumentServer versions 4.0.3 through 7.3.2. This flaw allows unauthenticated remote attackers to execute arbitrary code by supplying a specially crafted JavaScript file. With a CVSS score of 9.8, it presents a severe risk due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. While no public exploit code (Metasploit, Nuclei, ExploitDB) or active exploitation has been observed, and community discussion is minimal, the high CVSS score and FAUCET Risk Score of 81/100 warrant immediate attention.
