CVE-2008-3280

CWE-338Published: May 21, 2021· Updated: Jun 16, 2026

5.9
CVSS v3.1

Official Description

It was found that various OpenID Providers (OPs) had TLS Server Certificates that used weak keys, as a result of the Debian Predictable Random Number Generator (CVE-2008-0166). In combination with the DNS Cache Poisoning issue (CVE-2008-1447) and the fact that almost all SSL/TLS implementations do not consult CRLs (currently an untracked issue), this means that it is impossible to rely on these OPs.

Technical Analysis

CVE-2008-3280 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), with a CVSS base score of 5.9.

A proof-of-concept (PoC) exploit exists for CVE-2008-3280. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
