7.5 HIGH — AV:N/AC:L/Au:N/C:P/I:P/A:P

Description

The libCheckSignature function in crypto-utils.lib for OpenCA 0.9.1.6 and earlier only compares the serial of the signer's certificate and the one in the database, which can cause OpenCA to incorrectly accept a signature if the certificate's chain is trusted by OpenCA's chain directory, allowing remote attackers to spoof requests from other users.

Affected configurations

• openca openca (<= 0.9.1.6)
