CVE-2016-15005Network attack vector

CSRF bypass via predictably generated XSRF tokens

Published Dec 27, 2022 · Updated Apr 11, 2025

Cross-site request forgery in Dinever Golf before 0.3.0 allows remote attackers to bypass XSRF protections by predicting tokens. The randomBytes function in xsrf.go reseeds math/rand from the current Unix nanosecond time and selects token characters with rand.Intn, making generated values predictable. Exploitation requires user interaction and an application route that uses Golf's XSRF protection; successful prediction permits forged state-changing requests under the victim's authenticated session.
