Detailed Description |
The Cisco IOS, according to its version number, has a heap-based buffer overflow vulnerability (CISCO bug ID CSCei61732) in system timers. CISCO IOS 12.0x, 12.1x, 12.2x, 12.3x and 12.4x versions are vulnerable to a heap-based buffer overflow attack, caused by a boundary check error in system timers. By sending a specially-crafted packet, a remote attacker could execute arbitrary code with System service privileges and cause a denial of service on the affected system.
* Note: This check solely relied on the version number of the remote system to assess these vulnerabilities, so this might be a false positive. Also, it requires a read access SNMP community string to collect the version number. To provide this access, add the valid community string to the check item, "snmp/guessable/r" from the Policy Editor.
