CVE-2024-20767: ColdFusion | Improper Access Control (CWE-284)
Noroxi assessment
Priority: Now (action score 89/100)
- CISA has confirmed exploitation in the wild (Dec 16, 2024). Remediation deadline for US federal agencies: Jan 6, 2025.
- A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
- Probability of exploitation in the next 30 days: 98.5% (FIRST EPSS); higher than 99.9% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- According to the record, no fixed version is available yet.
Patch today or shut off access. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS
ColdFusion versions 2023.6, 2021.12 and earlier are affected by an Improper Access Control vulnerability that could result in arbitrary file system read. An attacker could leverage this vulnerability to access or modify restricted files. Exploitation of this issue does not require user interaction. Exploitation of this issue requires the admin panel be exposed to the internet.
