CVE-2018-16151 describes a vulnerability in strongSwan versions 4.x and 5.x before 5.7.0, specifically within its RSA implementation based on GMP. This flaw allows a remote attacker to forge PKCS#1 v1.5 signatures by not properly rejecting excess data after the algorithm OID, impacting products like Canonical and Debian distributions of strongSwan. The vulnerability carries a CVSS score of 7.5 (High), indicating a network-based attack with low complexity that can lead to high integrity impact, potentially enabling impersonation during IKEv2 authentication, especially when small public exponents are used. Currently, there is no evidence of active exploitation, no public exploit code available (Metasploit, Nuclei, ExploitDB), and minimal community discussion or media coverage, suggesting a low level of public awareness and exploitation.
