Detection & IOCsextracted from sources · hover to see the quote
- →Exploit requests contain the path traversal pattern `..CFIDE` within the URL, used to bypass access controls to reach the ColdFusion administration endpoints. ↗
- →Successful exploitation returns a WDDX-formatted response body containing `wddxPacket version=` with HTTP 200 status, which can be used as a detection signature. ↗
- →The query parameter `_cfclient=true` combined with `method=getBuildNumber` on a `.cfc` endpoint is a strong indicator of CVE-2023-26347 exploitation attempts. ↗
- →Shodan/FOFA fingerprinting queries for exposed ColdFusion instances: `http.component:"Adobe ColdFusion"`, `http.title:"coldfusion administrator login"`, `app="Adobe-ColdFusion"`. ↗
- ·The path traversal prefix `/hax/` in the exploit URL is an arbitrary directory segment; the critical bypass component is the `..CFIDE` traversal sequence. Detection rules should match on `..CFIDE` in the URL path regardless of the preceding directory name. ↗
- ·Vulnerability affects Adobe ColdFusion 2023.5 and earlier, and 2021.11 and earlier. Instances patched to 2023.6 or 2021.12+ are not vulnerable. ↗
