Comodo Firewall Pro CRC32 security bypass
| comodofirewallpro-crc32-security-bypass (32530) |  Medium Risk |
Description:
Comodo Firewall Pro (former Comodo Personal Firewall) could allow a local attacker to bypass security restrictions caused by weak cryptographic hashing. Comodo Firewall Pro uses cyclic redundancy check (CRC32) as a checksum function. A local attacker could create a malicious module with the same checksum to generate collisions and bypass protection.

- CVE-2007-1051: Comodo Firewall Pro (formerly Comodo Personal Firewall) 2.4.17.183 and earlier uses a weak cryptographic hashing function (CRC32) to identify trusted modules, which allows local users to bypass security protections by substituting modified modules that have the same CRC32 value.
Platforms Affected:
- Comodo Comodo Firewall Pro 2.4.16.174
- Comodo Comodo Firewall Pro 2.4.16.183
