CVE-2009-3027

29
FAUCET Score

CVE-2009-3027 describes a critical authentication bypass vulnerability in VRTSweb.exe, affecting numerous Symantec and Veritas products including Backup Exec, NetBackup Operations Manager, and various Storage Foundation and Cluster Server versions. This flaw allows remote attackers to trigger the unpacking of a WAR archive and execute arbitrary code by sending crafted data to TCP port 14300, due to improper validation of authentication requests. With a CVSS score of 10.0, this vulnerability is highly severe, requiring no authentication and having a low attack complexity, leading to complete compromise of confidentiality, integrity, and availability. While the EPSS score indicates a moderate likelihood of exploitation, there is no public exploit code available in Metasploit, Nuclei, or ExploitDB, and it currently lacks active exploitation or significant community discussion.
