Detailsinfo

A vulnerability, which was classified as critical, was found in Micca Auto Electronics Car Alarm System KE700/KE700+. This affects an unknown function. The manipulation with an unknown input leads to a entropy vulnerability. CWE is classifying the issue as CWE-331. The product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The Micca KE700 system relies on a 6-bit portion of an identifier for authentication within rolling codes, providing only 64 possible combinations. This low entropy allows an attacker to perform a brute-force attack against one component of the rolling code. Successful exploitation simplify an attacker to predict the next valid rolling code, granting unauthorized access to the vehicle.

The weakness was presented by Danilo Erazo. It is possible to read the advisory at asrg.io. This vulnerability is uniquely identified as CVE-2026-2541 since 02/15/2026.
