CVE-2013-3977

24
FAUCET Score

CVE-2013-3977 is an information disclosure vulnerability affecting IBM Sametime Meeting Server versions 8.x through 8.5.2.1 and 9.x through 9.0.0.1. This flaw allows unauthenticated remote attackers to enumerate meeting rooms owned by a specific user if a valid username is known. With a CVSS score of 4.3 (AV:N/AC:M/Au:N/C:P/I:N/A:N), it poses a low severity risk, primarily impacting confidentiality by revealing sensitive organizational structure. While not actively exploited in the wild, a Metasploit module exists for room name brute-forcing, and despite its age, its EPSS score indicates a higher than average likelihood of exploitation compared to most CVEs.
