Versions of the package cookiejar before 2.1.4 are vulnerable to Regular Expression Denial of Service (ReDoS) via the Cookie.parse function, which uses an insecure regular expression.
The product uses a regular expression with an inefficient, possibly exponential worst-case computational complexity that consumes excessive CPU cycles.
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Cookiejar | Cookiejar_project | * | 2.1.3 (including) |
| Node-cookiejar | Ubuntu | lunar | * |
| Node-cookiejar | Ubuntu | trusty | * |
| Node-cookiejar | Ubuntu | upstream | * |
| Node-cookiejar | Ubuntu | xenial | * |
Attackers can create crafted inputs that
intentionally cause the regular expression to use
excessive backtracking in a way that causes the CPU
consumption to spike.
