CVSS: 7.3EPSS: 0%CPEs: 10EXPL: 0CVE-2020-35452 – mod_auth_digest possible stack overflow by one nul byte
https://notcve.org/view.php?id=CVE-2020-35452
Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team could create one, though some particular compiler and/or compilation option might make it possible, with limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow Apache HTTP Server versiones 2.4.0 a 2.4.46 Un Digest nonce especialmente diseñado puede causar un desbordamiento de pila en la función mod_auth_digest. No existe reportes de que este desbordamiento sea explotable, ni el equipo del Servidor HTTP Apache podría crear uno, aunque algún compilador y/o opción de compilación particular podría hacerlo posible, con consecuencias limitadas de todos modos debido al tamaño (un solo byte) y el valor (cero bytes) del desbordamiento A flaw was found in Apache httpd. The mod_auth_digest has a single zero byte stack overflow. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • http://httpd.apache.org/security/vulnerabilities_24.html http://www.openwall.com/lists/oss-security/2021/06/10/5 https://lists.apache.org/thread.html/r7f2b70b621651548f4b6f027552f1dd91705d7111bb5d15cda0a68dd%40%3Cdev.httpd.apache.org%3E https://lists.apache.org/thread.html/rccb1b8225583a48c6360edc7a93cc97ae8b0215791e455dc607e7602%40%3Cannounce.httpd.apache.org%3E https://lists.apache.org/thread.html/re026d3da9d7824bd93b9f871c0fdda978d960c7e62d8c43cba8d0bf3%40%3Ccvs.httpd.apache.org%3E https://lists.debian.org/debian-lts-announce/2021/07/msg00006 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2020-11985
IP address spoofing when proxying using mod_remoteip and mod_rewrite For configurations using proxying with mod_remoteip and certain mod_rewrite rules, an attacker could spoof their IP address for logging and PHP scripts. Note this issue was fixed in Apache HTTP Server 2.4.24 but was retrospectively allocated a low severity CVE in 2020. Una falsificación de direcciones IP cuando se está usando un proxy por medio de mod_remoteip y mod_rewrite para las configuraciones que usan el proxy con mod_remoteip y determinadas reglas de mod_rewrite, un atacante podría falsificar su dirección IP para el registro y los scripts PHP. Note que este problema se corrigió en Apache HTTP Server versión 2.4.24, pero se le asignó retrospectivamente un CVE de poca gravedad en 2020 A flaw was found in the mod_remoteip module shipped with the httpd package. This flaw allows an attacker to spoof the IP address, resulting in the bypass of a mod_rewrite rule. • https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/r03ee478b3dda3e381fd6189366fa7af97c980d2f602846eef935277d%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/r09bb998baee74a2c316446bd1a41ae7f8d7049d09d9ff991471e8775%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/r3c5c3104813c1c5508b55564b66546933079250a46ce50eee90b2e36%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/r476d175be0aaf4a17680ef98c5153b4d336eaef76fb2224cc94c463a%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org • CWE-345: Insufficient Verification of Data Authenticity •
