Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Signature Spoofing by Key Recreation An attacker obtains an authoritative or reputable signer's private signature key by exploiting a cryptographic weakness in the signature algorithm or pseudorandom number generation and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

| description | The remote Cisco ASA device is affected by one or more of the following vulnerabilities : - A denial of service vulnerability exists due to improper clearing of unused memory blocks after an AnyConnect SSL VPN client disconnects. (CVE-2013-3415) - A denial of service vulnerability exists resulting from an error in the code that decrypts packets transiting an active VPN tunnel. (CVE-2013-5507) - A denial of service vulnerability exists due to improper handling of segmented Transparent Network Substrate (TNS) packets. (CVE-2013-5508) - An authentication bypass vulnerability exists resulting due to an error in handling a client crafted certificate during the authentication phase. (CVE-2013-5509) - An authentication bypass vulnerability exists due to improper parsing of the LDAP response packet received from a remote AAA LDAP server. (CVE-2013-5510) - An authentication bypass vulnerability exists due to an error in the implementation of the authentication-certificate option. (CVE-2013-5511) - A denial of service vulnerability exists due to improper handling of a race condition during inspection of HTTP packets by the HTTP DPI engine. (CVE-2013-5512) - A denial of service vulnerability exists due to the improper processing of unsupported DNS over TCP packets by the DNS inspection engine. (CVE-2013-5513) - A denial of service vulnerability exists resulting from the improper handling of crafted HTTPS requests for systems configured for Clientless SSL VPN. (CVE-2013-5515) - A denial of service condition can be caused by improper handling of crafted ICMP packets. (CVE-2013-5542) Note that the verification checks for the presence of CVE-2013-5513 and CVE-2013-5515 are best effort approaches and may result in potential false positives. |
