CVSS: 8.1EPSS: 95%CPEs: 16EXPL: 1CVE-2017-15715 – httpd: <FilesMatch> bypass with a trailing newline in the file name
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 •
