CVE-2025-34469Cowrie < 2.9.0 Unrestricted wget/curl Emulation Enables SSRF-Based DDoS Amplification
Medium 6.9
In plain English
A medium-severity server-side request forgery in Cowrie from Cowrie. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.7% (higher than 52% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
Cowrie versions prior to 2.9.0 contain a server-side request forgery (SSRF) vulnerability in the emulated shell implementation of wget and curl. In the default emulated shell configuration, these command emulations perform real outbound HTTP requests to attacker-supplied destinations. Because no outbound request rate limiting was enforced, unauthenticated remote attackers could repeatedly invoke these commands to generate unbounded HTTP traffic toward arbitrary third-party targets, allowing the Cowrie honeypot to be abused as a denial-of-service amplification node and masking the attacker’s true source address behind the honeypot’s IP.
