CVSS: 7.5EPSS: 2%CPEs: 36EXPL: 0CVE-2017-15710 – httpd: Out of bounds write in mod_authnz_ldap when using too small Accept-Language values
https://notcve.org/view.php?id=CVE-2017-15710
In Apache httpd 2.0.23 to 2.0.65, 2.2.0 to 2.2.34, and 2.4.0 to 2.4.29, mod_authnz_ldap, if configured with AuthLDAPCharsetConfig, uses the Accept-Language header value to lookup the right charset encoding when verifying the user's credentials. If the header value is not present in the charset conversion table, a fallback mechanism is used to truncate it to a two characters value to allow a quick retry (for example, 'en-US' is truncated to 'en'). A header value of less than two characters forces an out of bound write of one NUL byte to a memory location that is not part of the string. In the worst case, quite unlikely, the process would crash which could be used as a Denial of Service attack. In the more likely case, this memory is already reserved for future use and the issue has no effect at all. • http://www.openwall.com/lists/oss-security/2018/03/24/8 http://www.securityfocus.com/bid/103512 http://www.securitytracker.com/id/1040569 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-787: Out-of-bounds Write •
CVSS: 5.9EPSS: 1%CPEs: 18EXPL: 0CVE-2018-1301 – httpd: Out of bounds access after failure in reading the HTTP request
https://notcve.org/view.php?id=CVE-2018-1301
A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.30, due to an out of bound access after a size limit is reached by reading the HTTP header. This vulnerability is considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is classified as low risk for common server usage. Una petición especialmente manipulada podría haber provocado el cierre inesperado del servidor Apache HTTP en versiones anteriores a la 2.4.30, debido a un acceso fuera de límites tras alcanzar un límite de tamaño mediante la lectura de una cabecera HTTP. Esta vulnerabilidad se considera crítica si no es imposible desencadenarla en un modo que no sea de depuración (tanto a nivel de log como de build), por lo que se clasifica como vulnerabilidad de riesgo bajo para un uso común del servidor. • http://www.openwall.com/lists/oss-security/2018/03/24/2 http://www.securityfocus.com/bid/103515 http://www.securitytracker.com/id/1040573 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-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2017-15715
In Apache httpd 2.4.0 to 2.4.29, the expression specified in <FilesMatch> could match '$' to a newline character in a malicious filename, rather than matching only the end of the filename. This could be exploited in environments where uploads of some files are are externally blocked, but only by matching the trailing portion of the filename. En las versiones 2.4.0 hasta la 2.4.29 de Apache httpd, la expresión especificada en podría unir "$" con un carácter nueva línea o newline en un nombre de archivo malicioso, en lugar de interpretarse, únicamente, como el final del nombre de archivo. Esto se podría explotar en entornos donde las subidas de algunos archivos están bloqueadas de manera externa, pero solo uniendo la porción final del nombre del archivo. • https://github.com/whisp1830/CVE-2017-15715 http://www.openwall.com/lists/oss-security/2018/03/24/6 http://www.securityfocus.com/bid/103525 http://www.securitytracker.com/id/1040570 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& • CWE-20: Improper Input Validation CWE-787: Out-of-bounds Write •
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 •

rsyslog librelp version 1.2.14 and earlier contains a Buffer Overflow vulnerability in the checking of x509 certificates from a peer that can result in Remote code execution. This attack appear to be exploitable a remote attacker that can connect to rsyslog and trigger a stack buffer overflow by sending a specially crafted x509 certificate. rsyslog librelp en versiones 1.2.14 y anteriores contiene una vulnerabilidad de desbordamiento de búfer en la verificación de certificados x509 desde un peer que puede resultar en la ejecución remota de código. Parece que este ataque puede ser explotable debido a que un atacante remoto puede conectarse a rsyslog y desencadena un desbordamiento de búfer basado en pila mediante el envío de un certificado x509 especialmente manipulado. A stack-based buffer overflow was found in the way librelp parses X.509 certificates. By connecting or accepting connections from a remote peer, an attacker may use a specially crafted X.509 certificate to exploit this flaw and potentially execute arbitrary code. • https://github.com/s0/rsyslog-librelp-CVE-2018-1000140 https://github.com/s0/rsyslog-librelp-CVE-2018-1000140-fixed http://packetstormsecurity.com/files/172829/librelp-Remote-Code-Execution.html https://access.redhat.com/errata/RHSA-2018:1223 https://access.redhat.com/errata/RHSA-2018:1225 https://access.redhat.com/errata/RHSA-2018:1701 https://access.redhat.com/errata/RHSA-2018:1702 https://access.redhat.com/errata/RHSA-2018:1703 https://access.redhat.com/errata/RHSA-2018:1704 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
