5.9 · MEDIUMOverview
CVE-2015-5315 is a medium-severity vulnerability affecting w1.fi wpa_supplicant. It was published on February 21, 2018 and has a CVSS 3.0 base score of 5.9 (MEDIUM).
This vulnerability has a CVSS 3.0 base score of 5.9, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
The eap_pwd_process function in eap_peer/eap_pwd.c in wpa_supplicant 2.x before 2.6 does not validate that the reassembly buffer is large enough for the final fragment when EAP-pwd is enabled in a network configuration profile, which allows remote attackers to cause a denial of service (process termination) via a large final fragment in an EAP-pwd message.
Remediation
Check the references section for vendor advisories and patches from w1.fi. Update wpa_supplicant to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
