CVE-2021-44224 – Possible NULL dereference or SSRF in forward proxy configurations in Apache HTTP Server 2.4.51 and earlier
https://notcve.org/view.php?id=CVE-2021-44224
A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included). Un URI diseñado que es enviado a httpd configurado como proxy directo (ProxyRequests on) puede causar un fallo (desreferencia de puntero NULL) o, en el caso de configuraciones que mezclan declaraciones de proxy directo e inverso, puede permitir que las peticiones se dirijan a un endpoint de socket de dominio Unix declarado (Server Side Request Forgery). Este problema afecta a Apache HTTP Server versiones 2.4.7 hasta 2.4.51 (incluyéndola) There's a null pointer dereference and server-side request forgery flaw in httpd's mod_proxy module, when it is configured to be used as a forward proxy. A crafted packet could be sent on the adjacent network to the forward proxy that could cause a crash, or potentially SSRF via misdirected Unix Domain Socket requests. • http://httpd.apache.org/security/vulnerabilities_24.html http://seclists.org/fulldisclosure/2022/May/33 http://seclists.org/fulldisclosure/2022/May/35 http://seclists.org/fulldisclosure/2022/May/38 http://www.openwall.com/lists/oss-security/2021/12/20/3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BFSWOH4X77CV7AH7C4RMHUBDWKQDL4YH https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RGWILBORT67SHMSLYSQZG2NMXGCMPUZO https:// • CWE-476: NULL Pointer Dereference CWE-918: Server-Side Request Forgery (SSRF) •
CVE-2021-44790 – Possible buffer overflow when parsing multipart content in mod_lua of Apache HTTP Server 2.4.51 and earlier
https://notcve.org/view.php?id=CVE-2021-44790
A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier. Un cuerpo de petición cuidadosamente diseñado puede causar un desbordamiento de búfer en el analizador multiparte mod_lua (r:parsebody() llamado desde scripts Lua). El equipo de Apache httpd no presenta constancia de que se presente una explotación para esta vulnerabilidad, aunque podría ser posible diseñar uno. • https://www.exploit-db.com/exploits/51193 https://github.com/nuPacaChi/-CVE-2021-44790 http://httpd.apache.org/security/vulnerabilities_24.html http://packetstormsecurity.com/files/171631/Apache-2.4.x-Buffer-Overflow.html http://seclists.org/fulldisclosure/2022/May/33 http://seclists.org/fulldisclosure/2022/May/35 http://seclists.org/fulldisclosure/2022/May/38 http://www.openwall.com/lists/oss-security/2021/12/20/4 https://lists.fedoraproject.org/archives/list/package-announce • CWE-787: Out-of-bounds Write •
