Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 29.3% 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 SI-16 (Memory Protection) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2024-48854 is an off-by-one error (CWE-193) in the TIFF image codec within QNX SDP versions 8.0, 7.1, and 7.0. Published on 2025-01-14, this vulnerability enables an unauthenticated attacker to cause information disclosure in the context of the process using the image codec. It carries a CVSS v3.1 base score of 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N), indicating medium severity with low confidentiality impact and no impact on integrity or availability.
An unauthenticated attacker can exploit this vulnerability remotely over the network with low attack complexity and no privileges or user interaction required. Exploitation triggers the off-by-one error during TIFF image processing, potentially leaking sensitive data from the memory space of the affected process.
