Mailform Pro CGI 4.3.1.2 and earlier allows a remote unauthenticated attacker to cause a denial-of-service (DoS) condition.
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 |
|---|---|---|---|
| Mailform_pro_cgi | Synck | * | 4.3.1.2 (including) |
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.
