CVSS: 9.6EPSS: 0%CPEs: 12EXPL: 0CVE-2020-15810 – squid: HTTP Request Smuggling could result in cache poisoning
https://notcve.org/view.php?id=CVE-2020-15810
An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP Request Smuggling attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client, including browser scripts, to bypass local security and poison the proxy cache and any downstream caches with content from an arbitrary source. When configured for relaxed header parsing (the default), Squid relays headers containing whitespace characters to upstream servers. • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00012.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00017.html https://github.com/squid-cache/squid/security/advisories/GHSA-3365-q9qx-f98m https://lists.debian.org/debian-lts-announce/2020/10/msg00005.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BE6FKUN7IGTIR2MEEMWYDT7N5EJJLZI2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BMTFLVB7GLRF2C • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP Request Splitting attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client, including browser scripts, to bypass local security and poison the browser cache and any downstream caches with content from an arbitrary source. Squid uses a string search instead of parsing the Transfer-Encoding header to find chunked encoding. • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00012.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00017.html https://github.com/squid-cache/squid/security/advisories/GHSA-c7p8-xqhm-49wv https://lists.debian.org/debian-lts-announce/2020/10/msg00005.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BE6FKUN7IGTIR2MEEMWYDT7N5EJJLZI2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BMTFLVB7GLRF2C • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') CWE-697: Incorrect Comparison •
CVSS: 8.6EPSS: 1%CPEs: 12EXPL: 0CVE-2020-24606 – squid: Improper input validation could result in a DoS
https://notcve.org/view.php?id=CVE-2020-24606
Squid before 4.13 and 5.x before 5.0.4 allows a trusted peer to perform Denial of Service by consuming all available CPU cycles during handling of a crafted Cache Digest response message. This only occurs when cache_peer is used with the cache digests feature. The problem exists because peerDigestHandleReply() livelocking in peer_digest.cc mishandles EOF. Squid versiones anteriores a 4.13 y versiones 5.x anteriores a 5.0.4, permite que un peer de confianza lleve a cabo una Denegación de Servicio mediante el consumo de todos los ciclos de la CPU disponibles durante el manejo de un mensaje de respuesta de Cache Digest diseñado. Esto solo ocurre cuando cache_peer es usado con la funcionalidad cache digest. • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00012.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00017.html http://www.squid-cache.org/Versions/v4/changesets/SQUID-2020_9.patch https://github.com/squid-cache/squid/security/advisories/GHSA-vvj7-xjgq-g2jg https://lists.debian.org/debian-lts-announce/2020/10/msg00005.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BE6FKUN7IGTIR2MEEMWYDT7N5EJJLZI2 https://lists.fedoraproje • CWE-20: Improper Input Validation CWE-667: Improper Locking •

https://notcve.org/view.php?id=CVE-2020-14058
An issue was discovered in Squid before 4.12 and 5.x before 5.0.3. Due to use of a potentially dangerous function, Squid and the default certificate validation helper are vulnerable to a Denial of Service when opening a TLS connection to an attacker-controlled server for HTTPS. This occurs because unrecognized error values are mapped to NULL, but later code expects that each error value is mapped to a valid error string. Se detectó un problema en Squid versiones anteriores a 4.12 y versiones 5.x anteriores a 5.0.3. Debido al uso de una función potencialmente peligrosa, Squid y el asistente de comprobación de certificados predeterminado son vulnerables a una Denegación de Servicio al abrir una conexión TLS en un servidor controlado por el atacante por HTTPS. • http://www.squid-cache.org/Advisories/SQUID-2020_6.txt http://www.squid-cache.org/Versions/v4/changesets/squid-4-93f5fda134a2a010b84ffedbe833d670e63ba4be.patch http://www.squid-cache.org/Versions/v5/changesets/squid-5-c6d1a4f6a2cbebceebc8a3fcd8f539ceb7b7f723.patch https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3RG5FGSTCAYVIJPJHIY3MRZ7NFT6HDO7 https://security.netapp.com/advisory/ntap-20210312-0001 https://access.redhat.com/security/cve/CVE-2020-14058 https://bugzilla.redhat.com/show • CWE-676: Use of Potentially Dangerous Function •
