Published: 06 January 2025
Summary
CVE-2024-54767 is a high-severity Observable Discrepancy (CWE-203) vulnerability. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 7.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 AC-14 (Permitted Actions Without Identification or Authentication) and AC-3 (Access Enforcement).
Deeper analysis
CVE-2024-54767 is an access control vulnerability affecting the /juis_boxinfo.xml endpoint on AVM FRITZ!Box 7530 AX devices running firmware version 7.59. The flaw permits unauthenticated retrieval of sensitive device information and carries a CVSS 3.1 base score of 7.5, reflecting network attack vector, low complexity, and high impact on confidentiality. The issue is tracked under CWE-203.
An unauthenticated remote attacker can send crafted requests to the affected endpoint and obtain sensitive information without any credentials. Exploitation requires no user interaction and can be performed over the network.
The vendor disputes the report, stating that the behavior cannot be reproduced under supported configurations and appears tied to an unintended direct internet exposure of the device. No official patches or mitigation guidance are referenced in the supplied sources.
The associated EPSS score has remained flat at 0.0919 with no material increase since disclosure.
