CVE-2013-3563

CVE-2013-3563 describes a stack-based buffer overflow in the db_netserver component of Lianja SQL Server versions prior to 1.0.0RC5.2. This vulnerability allows unauthenticated remote attackers to cause a denial of service by crashing the daemon or potentially execute arbitrary code by sending a crafted string to TCP port 8001. With a CVSS score of 7.5, it is considered highly severe due to its network-based attack vector and low attack complexity, enabling potential compromise of confidentiality, integrity, and availability. While not listed on the KEV catalog, a Metasploit module exists, indicating readily available exploit code, though there is no evidence of active exploitation or significant community discussion.
