iDefense Security Advisory 09.27.07 - Remote exploitation of multiple buffer overflow vulnerabilities in Computer Associates International Inc.'s (CA) BrightStor HSM allows attackers to execute arbitrary code with SYSTEM privileges. These problems specifically exist within various command handlers in the CsAgent service. There are eleven command handlers that contain one or more stack based buffer overflow vulnerabilities each. All of these vulnerabilities are simple sprintf() calls that overflow fixed size stack buffers with attacker supplied data. Additionally, there are five command handlers that are vulnerable to integer overflow vulnerabilities. In addition to this, the function responsible for reading in and dispatching a request to the appropriate handler also contains an integer overflow vulnerability. iDefense has confirmed the existence of these vulnerabilities in Computer Associates BrightStor HSM version r11.5. Previous versions may also be affected.
3d9fe570146e0a06df94ce7623638630d7d96e1cc82bd6f5fff193c4ce9c5e51Multiple vulnerabilities exist in the CsAgent service that can allow a remote attacker to execute arbitrary code or cause a denial of service condition. The first set of vulnerabilities, CVE-2007-5082, occur due to insufficient bounds checking in multiple CsAgent service commands. The second set of vulnerabilities, CVE-2007-5083, occur due to insufficient validation of integer values in multiple CsAgent service commands, which can lead to buffer overflow. The third set of vulnerabilities, CVE-2007-5084, occur due to insufficient validation of strings used in SQL statements in multiple CsAgent service commands.
