CVE-2021-30004alpinehostapd+13
EPSS score1.64%
In wpa_supplicant and hostapd 2.9, forging attacks may occur because AlgorithmIdentifier parameters are mishandled in tls/pkcs1.c and tls/x509v3.c.CVE-2015-4143debianwpa+4EPSS score3.47%
The EAP-pwd server and peer implementation in hostapd and wpa_supplicant 1.0 through 2.4 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted (1) Commit or (2) Confirm message payload.CVE-2015-4144debianwpa+4EPSS score3.38%
The EAP-pwd server and peer implementation in hostapd and wpa_supplicant 1.0 through 2.4 does not validate that a message is long enough to contain the Total-Length field, which allows remote attackers to cause a denial of service (crash) via a crafted message.CVE-2015-4146debianwpa+4EPSS score3.45%
The EAP-pwd peer implementation in hostapd and wpa_supplicant 1.0 through 2.4 does not clear the L (Length) and M (More) flags before determining if a response should be fragmented, which allows remote attackers to cause a denial of service (crash) via a crafted message.CVE-2015-4141debianwpa+4EPSS score2.97%
The WPS UPnP function in hostapd, when using WPS AP, and wpa_supplicant, when using WPS external registrar (ER), 0.7.0 through 2.4 allows remote attackers to cause a denial of service (crash) via a negative chunk length, which triggers an out-of-bounds read or heap-based buffer overflow.CVE-2015-4145debianwpa+4EPSS score3.38%
The EAP-pwd server and peer implementation in hostapd and wpa_supplicant 1.0 through 2.4 does not validate a fragment is already being processed, which allows remote attackers to cause a denial of service (memory leak) via a crafted message.CVE-2015-4142debianhostapd+11EPSS score4.17%
Integer underflow in the WMM Action frame parser in hostapd 0.5.5 through 2.4 and wpa_supplicant 0.7.0 through 2.4, when used for AP mode MLME/SME functionality, allows remote attackers to cause a denial of service (crash) via a crafted frame, which triggers an out-of-bounds read.CVE-2015-8041debianwpa+4EPSS score3.41%
Multiple integer overflows in the NDEF record parser in hostapd before 2.5 and wpa_supplicant before 2.5 allow remote attackers to cause a denial of service (process crash or infinite loop) via a large payload length field value in an (1) WPS or (2) P2P NFC NDEF record, which triggers an out-of-bounds read.CVE-2016-4476alpinewpa_supplicant+5EPSS score2.86%
hostapd 0.6.7 through 2.5 and wpa_supplicant 0.6.7 through 2.5 do not reject \n and \r characters in passphrase parameters, which allows remote attackers to cause a denial of service (daemon outage) via a crafted WPS operation.CVE-2016-10743debianwpa+2EPSS score2.35%
hostapd before 2.6 does not prevent use of the low-quality PRNG that is reached by an os_random() function call.CVE-2025-24912jouni malinenhostapd+12EPSS score0.78%
hostapd fails to process crafted RADIUS packets properly. When hostapd authenticates wi-fi devices with RADIUS authentication, an attacker in the position between the hostapd and the RADIUS server may inject crafted RADIUS packets and force RADIUS authentications to fail.CVE-2020-12695alpinehostapd+238EPSS score15.19%
The Open Connectivity Foundation UPnP specification before 2020-04-17 does not forbid the acceptance of a subscription request with a delivery URL on a different network segment than the fully qualified event-subscription URL, aka the CallStranger issue.CVE-2014-3686canonicalubuntu_linux+12EPSS score4.95%
wpa_supplicant and hostapd 0.7.2 through 2.2, when running with certain configurations and using wpa_cli or hostapd_cli with action scripts, allows remote attackers to execute arbitrary commands via a crafted frame.CVE-2022-37660debianwpa+2EPSS score0.38%
In hostapd 2.10 and earlier, the PKEX code remains active even after a successful PKEX association. An attacker that successfully bootstrapped public keys with another entity using PKEX in the past, will be able to subvert a future bootstrapping by passively observing public keys, re-using the encrypting element Qi and subtracting it from the captured message M (X = M - Qi). This will result in the public ephemeral key X; the only element required to subvert the PKEX association.CVE-2022-23303alpinehostapd+9EPSS score3.05%
The implementations of SAE in hostapd before 2.10 and wpa_supplicant before 2.10 are vulnerable to side channel attacks as a result of cache access patterns. NOTE: this issue exists because of an incomplete fix for CVE-2019-9494.CVE-2022-23304alpinehostapd+5EPSS score1.91%
The implementations of EAP-pwd in hostapd before 2.10 and wpa_supplicant before 2.10 are vulnerable to side-channel attacks as a result of cache access patterns. NOTE: this issue exists because of an incomplete fix for CVE-2019-9495.CVE-2012-2389w1.fihostapdEPSS score0.35%
hostapd 0.7.3, and possibly other versions before 1.0, uses 0644 permissions for /etc/hostapd/hostapd.conf, which might allow local users to obtain sensitive information such as credentials.CVE-2012-4445debianhostapd+2EPSS score4.22%
Heap-based buffer overflow in the eap_server_tls_process_fragment function in eap_server_tls_common.c in the EAP authentication server in hostapd 0.6 through 1.0 allows remote attackers to cause a denial of service (crash or abort) via a small "TLS Message Length" value in an EAP-TLS message with the "More Fragments" flag set.CVE-2017-13086alpinehostapd+16EPSS score2.05%
Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Tunneled Direct-Link Setup (TDLS) Peer Key (TPK) during the TDLS handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames.CVE-2017-13082alpinehostapd+16EPSS score4.58%
Wi-Fi Protected Access (WPA and WPA2) that supports IEEE 802.11r allows reinstallation of the Pairwise Transient Key (PTK) Temporal Key (TK) during the fast BSS transmission (FT) handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames.
