A series of four vulnerabilities in the Common Unix Printing System can enable remote code execution (RCE) and facilitate distributed denial of service (DDoS) attacks.
The possibility of exploiting Cups for DDoS attacks is particularly concerning because it requires minimal resources, making it easier for attackers to disrupt services.
Researchers found that an attacker could send a single crafted packet to a Cups server, which would generate a larger request to a target, initiating DDoS.
Utilizing a modern hyperscaler platform, a DDoS attack could potentially be launched at an extremely low cost, underlining the convenience and threat of this vulnerability.
