CVSS: 9.8EPSS: 27%CPEs: 24EXPL: 7CVE-2018-17456 – Git Submodule - Arbitrary Code Execution
https://notcve.org/view.php?id=CVE-2018-17456
Git before 2.14.5, 2.15.x before 2.15.3, 2.16.x before 2.16.5, 2.17.x before 2.17.2, 2.18.x before 2.18.1, and 2.19.x before 2.19.1 allows remote code execution during processing of a recursive "git clone" of a superproject if a .gitmodules file has a URL field beginning with a '-' character. Git en versiones anteriores a la 2.14.5, versiones 2.15.x anteriores a la 2.15.3, versiones 2.16.x anteriores a la 2.16.5, versiones 2.17.x anteriores a la 2.17.2, versiones 2.18.x anteriores a la 2.18.1 y versiones 2.19.x anteriores a la 2.19.1 permite la ejecución remota de código durante el procesamiento de un "clon de git" recursivo de un superproyecto si un archivo .gitmodules tiene un campo URL que comienza por un carácter "-". An option injection flaw has been discovered in git when it recursively clones a repository with sub-modules. A remote attacker may configure a malicious repository and trick a user into recursively cloning it, thus executing arbitrary commands on the victim's machine. • https://www.exploit-db.com/exploits/45631 https://www.exploit-db.com/exploits/45548 https://github.com/AnonymKing/CVE-2018-17456 https://github.com/matlink/CVE-2018-17456 https://github.com/shpik-kr/CVE-2018-17456 https://github.com/799600966/CVE-2018-17456 https://github.com/KKkai0315/CVE-2018-17456 http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00003.html http://packetstormsecurity.com/files/152173/Sourcetree-Git-Arbitrary-Code-Execution-URL-Handling.html http:/ • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') •

https://notcve.org/view.php?id=CVE-2018-11763
In Apache HTTP Server 2.4.17 to 2.4.34, by sending continuous, large SETTINGS frames a client can occupy a connection, server thread and CPU time without any connection timeout coming to effect. This affects only HTTP/2 connections. A possible mitigation is to not enable the h2 protocol. En Apache HTTP Server, de la versión 2.4.17 a la 2.4.34, mediante el envío continuo de tramas SETTINGS grandes, un cliente puede ocupar una conexión, hilo del servidor y tiempo de CPU sin que se active ningún agotamiento del tiempo de conexión. Esto solo afecta a las conexiones HTTP/2. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00030.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00056.html http://www.securityfocus.com/bid/105414 http://www.securitytracker.com/id/1041713 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/56c2e7cc9deb1c12a843d0dc251ea7f • CWE-20: Improper Input Validation •

An information leak vulnerability was found in Undertow. If all headers are not written out in the first write() call then the code that handles flushing the buffer will always write out the full contents of the writevBuffer buffer, which may contain data from previous requests. Se ha encontrado una vulnerabilidad de fuga de información en Undertow.
