IBM Concert Software 1.0.0 through 1.1.0 could allow a remote attacker to cause a denial of service using a specially crafted regular expression that would cause excessive resource consumption.
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 |
|---|---|---|---|
| Concert | Ibm | 1.0.0 (including) | 2.0.0 (excluding) |
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.
