CVE-2025-59350

Timing attacks against Proxy’s basic authentication are possible

Published Sep 17, 2025 CVSS 4.0 · 2.7 Low EPSS < 1% KEV · Not listed
Description
Dragonfly is an open source P2P-based file distribution and image acceleration system. Prior to 2.1.0, the access control mechanism for the Proxy feature uses simple string comparisons and is therefore vulnerable to timing attacks. An attacker may try to guess the password one character at a time by sending all possible characters to a vulnerable mechanism and measuring the comparison instruction’s execution times. This vulnerability is fixed in 2.1.0.
