UNKNOWN Summary
Race condition in the HTTP Deep Packet Inspection (DPI) feature in Cisco Adaptive Security Appliance (ASA) Software 8.2.x before 8.2(5.46), 8.3.x before 8.3(2.39), 8.4.x before 8.4(5.5), 8.5.x before 8.5(1.18), 8.6.x before 8.6(1.12), 8.7.x before 8.7(1.4), 9.0.x before 9.0(1.4), and 9.1.x before 9.1(1.2), in certain conditions involving the spoof-server option or ActiveX or Java response inspection, allows remote attackers to cause a denial of service (device reload) via a crafted HTTP response, aka Bug ID CSCud37992.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Leveraging Race Conditions This attack targets a race condition occurring when multiple processes access and manipulate the same resource concurrently and the outcome of the execution depends on the particular order in which the access takes place. The attacker can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance a race condition can occur while accessing a file, the attacker can trick the system by replacing the original file with his version and cause the system to read the malicious file.
- Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. The typical example is the file access. The attacker can leverage a file access race condition by "running the race", meaning that he would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the attacker could do something such as replace the file and cause an escalation of privilege.

| 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. |
