A potential DoS vulnerability was discovered in Gitlab CE/EE versions 13.7 before 14.7.7, all versions starting from 14.8 before 14.8.5, all versions starting from 14.9 before 14.9.2 allowed an attacker to trigger high CPU usage via a special crafted input added in Issues, Merge requests, Milestones, Snippets, Wiki pages, etc.
The product receives input that is expected to specify a quantity (such as size or length), but it does not validate or incorrectly validates that the quantity has the required properties.
Name | Vendor | Start Version | End Version |
---|---|---|---|
Gitlab | Gitlab | 13.7.0 (including) | 14.7.7 (excluding) |
Gitlab | Gitlab | 14.8.0 (including) | 14.8.5 (excluding) |
Gitlab | Gitlab | 14.9.0 (including) | 14.9.2 (excluding) |
Gitlab | Ubuntu | esm-apps/xenial | * |
Gitlab | Ubuntu | trusty | * |
Gitlab | Ubuntu | xenial | * |
Specified quantities include size, length, frequency, price, rate, number of operations, time, and others. Code may rely on specified quantities to allocate resources, perform calculations, control iteration, etc. When the quantity is not properly validated, then attackers can specify malicious quantities to cause excessive resource allocation, trigger unexpected failures, enable buffer overflows, etc.
