CVSS: 5.9EPSS: 1%CPEs: 24EXPL: 0CVE-2019-9494 – The implementations of SAE in hostapd and wpa_supplicant are vulnerable to side-channel attacks
https://notcve.org/view.php?id=CVE-2019-9494
The implementations of SAE in hostapd and wpa_supplicant are vulnerable to side channel attacks as a result of observable timing differences and cache access patterns. An attacker may be able to gain leaked information from a side channel attack that can be used for full password recovery. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.7 are affected. Las implementaciones SAE en hostapd y wpa_supplicant son vulnerables a los ataques de canal lateral (side channel) como resultado de diferencias de tiempo observables y patrones de acceso a la caché. Un atacante puede conseguir información filtrada de un ataque de canal lateral (side channel) que pueda ser usado para la recuperación completa de la contraseña. • http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00021.html http://packetstormsecurity.com/files/152914/FreeBSD-Security-Advisory-FreeBSD-SA-19-03.wpa.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/56OBBOJJSKRTDGEXZOVFSTP4HDSDBLAE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SVMJOFEYBGXZLFF5IOLW67SSOPKFEJP3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TDOZGR3T7FVO5JSZWK2QPR7AOFIEJTIZ https:&# • CWE-203: Observable Discrepancy CWE-208: Observable Timing Discrepancy CWE-524: Use of Cache Containing Sensitive Information •

https://notcve.org/view.php?id=CVE-2019-9495
The implementations of EAP-PWD in hostapd and wpa_supplicant are vulnerable to side-channel attacks as a result of cache access patterns. All versions of hostapd and wpa_supplicant with EAP-PWD support are vulnerable. The ability to install and execute applications is necessary for a successful attack. Memory access patterns are visible in a shared cache. Weak passwords may be cracked. • http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00021.html http://packetstormsecurity.com/files/152914/FreeBSD-Security-Advisory-FreeBSD-SA-19-03.wpa.html https://lists.debian.org/debian-lts-announce/2019/07/msg00030.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/56OBBOJJSKRTDGEXZOVFSTP4HDSDBLAE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SVMJOFEYBGXZLFF5IOLW67SSOPKFEJP3 https://lists.fedoraproject.org/archives/list/p • CWE-203: Observable Discrepancy CWE-524: Use of Cache Containing Sensitive Information •

https://notcve.org/view.php?id=CVE-2019-9498
The implementations of EAP-PWD in hostapd EAP Server, when built against a crypto library missing explicit validation on imported elements, do not validate the scalar and element values in EAP-pwd-Commit. An attacker may be able to use invalid scalar/element values to complete authentication, gaining session key and network access without needing or learning the password. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.4 are affected. Both hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior to and including version 2.7 are affected. Las implementaciones del componente EAP-PWD en hostapd en EAP Server, cuando se construyen contra una biblioteca criptográfica sin comprobación explícita en elementos importados, no comprueban los valores escalares y de elementos en EAP-pwd-Commit. • http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00021.html https://lists.debian.org/debian-lts-announce/2019/07/msg00030.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/56OBBOJJSKRTDGEXZOVFSTP4HDSDBLAE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SVMJOFEYBGXZLFF5IOLW67SSOPKFEJP3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TDOZGR3T7FVO5JSZWK2QPR7AOFIEJTIZ https://seclists.org/bugtraq& • CWE-287: Improper Authentication CWE-346: Origin Validation Error •
