Intel CSME/SPS timing discrepancy

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Intel CSME and SPS (the affected version unknown). It has been classified as problematic. This affects an unknown part. The manipulation with an unknown input leads to a timing discrepancy vulnerability. CWE is classifying the issue as CWE-208. Two separate operations in a product require different amounts of time to complete, in a way that is observable to an actor and reveals security-relevant information about the state of the product, such as whether a particular operation was successful or not. This is going to have an impact on confidentiality. The summary by CVE is:

Observable timing discrepancy in firmware for some Intel(R) CSME and Intel(R) SPS may allow a privileged user to potentially enable information disclosure via local access.

The advisory is shared at intel.com. This vulnerability is uniquely identified as CVE-2025-20067 since 10/11/2024. The exploitability is told to be easy. An attack has to be approached locally. Additional levels of successful authentication are needed for exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1592 for this issue.

Upgrading eliminates this vulnerability. Intel recommends that each affected platform should be updated to its latest version. For more information, visit https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-01280.html.
