Oracle iPlanet Web Proxy Server 4.0 < 4.0.25 NSS Signature Verification Vulnerability
High Nessus Plugin ID 82994
SynopsisThe remote proxy web server is affected by a signature forgery vulnerability.
DescriptionAccording to its self-reported version, the Oracle iPlanet Web Proxy Server installed on the remote host is version 4.0 prior to 4.0.25. It is, therefore, affected by a flaw in the Network Security Services (NSS) library due to improper parsing of ASN.1 values in an RSA signature. A man-in-the-middle attacker, using a crafted certificate, can exploit this to forge RSA signatures, such as SSL certificates.
Note that Oracle iPlanet Web Proxy Server was formerly known as Sun Java System Web Proxy Server.
SolutionUpgrade to Oracle iPlanet Web Proxy Server 4.0.25 or later.
