Detailsinfo

A vulnerability, which was classified as critical, was found in Hostapd up to 2.5. Affected is the function rand/random of the component EAP Mode. The manipulation with an unknown input leads to a entropy vulnerability (PRNG). 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. CVE summarizes:

hostapd before 2.6, in EAP mode, makes calls to the rand() and random() standard library functions without any preceding srand() or srandom() call, which results in inappropriate use of deterministic values. This was fixed in conjunction with CVE-2016-10743.

The weakness was released 02/28/2020 as not defined mailinglist post (Full-Disclosure). The advisory is available at seclists.org. This vulnerability is traded as CVE-2019-10064 since 03/26/2019. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1600.001 by the MITRE ATT&CK project.

Upgrading to version 2.6 eliminates this vulnerability.
