CVE-2005-0039 describes a vulnerability in specific IPsec configurations, particularly when using ESP in tunnel mode, higher-layer integrity protection, or AH, affecting nissc ipsec products. Remote attackers can decrypt IPsec communications by manipulating outer packet fields, such as destination address, header length, or protocol field, to induce ICMP messages containing plaintext from the inner packet. This medium-severity vulnerability (CVSS 6.4) requires low attack complexity and no authentication, allowing for partial confidentiality and integrity impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage for this vulnerability.
