CVSS: 5.3EPSS: 0%CPEs: 16EXPL: 0CVE-2018-1283 – httpd: Improper handling of headers in mod_session can allow a remote user to modify session data for CGI applications
https://notcve.org/view.php?id=CVE-2018-1283
In Apache httpd 2.4.0 to 2.4.29, when mod_session is configured to forward its session data to CGI applications (SessionEnv on, not the default), a remote user may influence their content by using a "Session" header. This comes from the "HTTP_SESSION" variable name used by mod_session to forward its data to CGIs, since the prefix "HTTP_" is also used by the Apache HTTP Server to pass HTTP header fields, per CGI specifications. En Apache httpd, versiones 2.4.0 hasta la 2.4.29, cuando se configura mod_session para que reenvíe sus datos de sesión a aplicaciones CGI (SessionEnv habilitado, no por defecto), un usuario remoto podría influir en su contenido empleando una cabecera "Session". Esto viene del nombre de variable "HTTP_SESSION", empleado por mod_session para reenviar sus datos a interfaces de entrada común (CGI), dado que el prefijo "HTTP_" también es utilizado por el servidor Apache HTTP para pasar sus campos de cabecera HTTP, por especificaciones CGI. It has been discovered that the mod_session module of Apache HTTP Server (httpd), through version 2.4.29, has an improper input validation flaw in the way it handles HTTP session headers in some configurations. • http://www.openwall.com/lists/oss-security/2018/03/24/4 http://www.securityfocus.com/bid/103520 http://www.securitytracker.com/id/1040568 https://access.redhat.com/errata/RHSA-2018:3558 https://access.redhat.com/errata/RHSA-2019:0366 https://access.redhat.com/errata/RHSA-2019:0367 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.ht • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2017-9798
Apache httpd allows remote attackers to read secret data from process memory if the Limit directive can be set in a user's .htaccess file, or if httpd.conf has certain misconfigurations, aka Optionsbleed. This affects the Apache HTTP Server through 2.2.34 and 2.4.x through 2.4.27. The attacker sends an unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue and thus secret data is not always sent, and the specific data depends on many factors including configuration. Exploitation with .htaccess can be blocked with a patch to the ap_limit_section function in server/core.c. • https://www.exploit-db.com/exploits/42745 https://github.com/nitrado/CVE-2017-9798 https://github.com/l0n3rs/CVE-2017-9798 http://openwall.com/lists/oss-security/2017/09/18/2 http://www.debian.org/security/2017/dsa-3980 http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.oracle.com/technetwork/securi • CWE-416: Use After Free •
CVSS: 9.1EPSS: 46%CPEs: 34EXPL: 0CVE-2017-9788 – httpd: Uninitialized memory reflection in mod_auth_digest
https://notcve.org/view.php?id=CVE-2017-9788
In Apache httpd before 2.2.34 and 2.4.x before 2.4.27, the value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments by mod_auth_digest. Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault in other cases resulting in denial of service. En Apache httpd, en versiones anteriores a la 2.2.34 y en versiones 2.4.x anteriores a la 2.4.27, el valor placeholder en cabeceras [Proxy-]Authorization del tipo 'Digest' no se inicializó o reinició antes de o entre las asignaciones sucesivas key=value por mod_auth_digest. Proporcionar una clave inicial sin asignación "=" podría reflejar el valor obsoleto de la memoria agrupada no inicializada utilizada por la petición anterior. Esto podría dar lugar al filtrado de información potencialmente confidencial y, en otros casos, a un fallo de segmentación que daría como resultado una denegación de servicio (DoS) It was discovered that the httpd's mod_auth_digest module did not properly initialize memory before using it when processing certain headers related to digest authentication. • http://www.debian.org/security/2017/dsa-3913 http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/99569 http://www.securitytracker.com/id/1038906 https://access.redhat.com/errata/RHSA-2017:2478 https://access.redhat.com/errata/RHSA-2017:2479 https://access.redhat.com/errata/RHSA-2017:2483 https://access.redhat.com/errata/RHSA-2017:2708 https://access.redhat.com/errata/RHSA-2017:2709 https://access.redhat.com/errata/RHS • CWE-20: Improper Input Validation CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-456: Missing Initialization of a Variable •

In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port. En Apache httpd, en versiones 2.2.x anteriores a la 2.2.33 y versiones 2.4.x anteriores a la 2.4.26, mod_ssl podría desreferenciar un puntero NULL cuando los módulos de terceros llaman a ap_hook_process_connection() durante una petición HTTP a un puerto HTPS. A NULL pointer dereference flaw was found in the httpd's mod_ssl module. A remote attacker could use this flaw to cause an httpd child process to crash if another module used by httpd called a certain API function during the processing of an HTTPS request. • http://www.debian.org/security/2017/dsa-3896 http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/99134 http://www.securitytracker.com/id/1038711 https://access.redhat.com/errata/RHSA-2017:2478 https://access.redhat.com/errata/RHSA-2017:2479 https://access.redhat.com/errata/RHSA-2017:2483 https://access.redhat.com/errata/RHSA-2017:3193 https://access.redhat.com/errata/RHSA-2017:3194 https://access.redhat.com/errata/RHS • CWE-476: NULL Pointer Dereference •
