CVE-2004-2682: PeerSec MatrixSSL before 1.1 does not implement RSA blinding, which allows context-dependent attackers to o...

Security readout for executives and security teams

Older PeerSec MatrixSSL versions before 1.1 lack RSA blinding. In some deployment contexts, an attacker who can measure cryptographic timing differences may be able to recover a server private key. That could undermine TLS confidentiality and identity for affected services. Exposure is most likely in legacy products, embedded systems, or services that bundled PeerSec MatrixSSL before 1.1 and still use RSA private-key operations. The source bundle does not provide CPEs or a full affected-product list. Treat this as a legacy cryptographic exposure with potentially high impact but uncertain exploitability. Prioritize internet-facing or high-trust systems using old embedded TLS stacks, especially where private-key compromise would affect customers or production identity. Mitigation focus: Inventory software and firmware for PeerSec MatrixSSL usage.; Confirm whether any instance is MatrixSSL before 1.1.; Upgrade affected MatrixSSL deployments to 1.1 or later where supported..
