CVE-2002-0515 describes an information disclosure vulnerability in IPFilter 3.4.25 and earlier, where remote attackers can identify filtered ports. This is possible because the software sets a different Time-to-Live (TTL) value for filtered ports compared to unfiltered ones. With a CVSS score of 5.0, this low-complexity network-based attack allows an unauthenticated attacker to gain partial confidentiality, but has no impact on integrity or availability. There is no evidence of active exploitation, publicly available exploit code, or significant community discussion surrounding this vulnerability.
