CVE-2019-9636 – python: Information Disclosure due to urlsplit improper NFKC normalization
https://notcve.org/view.php?id=CVE-2019-9636
Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is affected by: Improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization. The impact is: Information disclosure (credentials, cookies, etc. that are cached against a given hostname). The components are: urllib.parse.urlsplit, urllib.parse.urlparse. The attack vector is: A specially crafted URL could be incorrectly parsed to locate cookies or authentication data and send that information to a different host than when parsed correctly. This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.7, v3.5.8, v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1; v3.7.3, v3.7.3rc1, v3.7.4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1, v3.7.8, v3.7.8rc1, v3.7.9. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00092.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00097.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00050.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00042.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html http://www.securityfocus.com/bid/107400 https://access. • CWE-172: Encoding Error •
CVE-2018-17189 – httpd: mod_http2: DoS via slow, unneeded request bodies
https://notcve.org/view.php?id=CVE-2018-17189
In Apache HTTP server versions 2.4.37 and prior, by sending request bodies in a slow loris way to plain resources, the h2 stream for that request unnecessarily occupied a server thread cleaning up that incoming data. This affects only HTTP/2 (mod_http2) connections. En Apache HTTP Server, en sus versiones 2.4.37 y anteriores, mediante el envío de cuerpos de respuesta mediante la técnica del "slow loris" a recursos planos, la transmisión h2 para esa petición ocupó de forma innecesaria un hilo de servidor que limpiaba tales datos entrantes. Esto afecta solo a las conexiones HTTP/2 (mod_http2). • http://www.securityfocus.com/bid/106685 https://access.redhat.com/errata/RHSA-2019:3932 https://access.redhat.com/errata/RHSA-2019:3933 https://access.redhat.com/errata/RHSA-2019:3935 https://access.redhat.com/errata/RHSA-2019:4126 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.html/84a3714f0878781f6ed84473d1a503d2cc382277e100450209231830%40%3Ccvs.httpd.apache • CWE-400: Uncontrolled Resource Consumption •
CVE-2018-15473 – OpenSSH < 7.7 - User Enumeration
https://notcve.org/view.php?id=CVE-2018-15473
OpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c. OpenSSH hasta la versión 7.7 es propenso a una vulnerabilidad de enumeración de usuarios debido a que no retrasa el rescate de un usuario de autenticación no válido hasta que el paquete que contiene la petición haya sido analizado completamente. Esto está relacionado con auth2-gss.c, auth2-hostbased.c, y auth2-pubkey.c. A user enumeration vulnerability flaw was found in OpenSSH, though version 7.7. The vulnerability occurs by not delaying bailout for an invalid authenticated user until after the packet containing the request has been fully parsed. • https://www.exploit-db.com/exploits/45939 https://www.exploit-db.com/exploits/45233 https://www.exploit-db.com/exploits/45210 https://github.com/Rhynorater/CVE-2018-15473-Exploit https://github.com/r3dxpl0it/CVE-2018-15473 https://github.com/Sait-Nuri/CVE-2018-15473 https://github.com/LINYIKAI/CVE-2018-15473-exp https://github.com/MrDottt/CVE-2018-15473 https://github.com/yZ1337/CVE-2018-15473 https://github.com/1stPeak/CVE-2018-15473 https://github.com/0xrobiu • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2017-15906 – openssh: Improper write operations in readonly mode allow for zero-length file creation
https://notcve.org/view.php?id=CVE-2017-15906
The process_open function in sftp-server.c in OpenSSH before 7.6 does not properly prevent write operations in readonly mode, which allows attackers to create zero-length files. La función process_open en sftp-server.c en OpenSSH, en versiones anteriores a la 7.6, no evita correctamente las operaciones de escritura en el modo readonly, lo que permite que los atacantes creen archivos de longitud cero. • http://www.securityfocus.com/bid/101552 https://access.redhat.com/errata/RHSA-2018:0980 https://cert-portal.siemens.com/productcert/pdf/ssa-412672.pdf https://github.com/openbsd/src/commit/a6981567e8e215acc1ef690c8dbb30f2d9b00a19 https://lists.debian.org/debian-lts-announce/2018/09/msg00010.html https://security.gentoo.org/glsa/201801-05 https://security.netapp.com/advisory/ntap-20180423-0004 https://www.openssh.com/txt/release-7.6 https://www.oracle.com/security-alerts/cpujan2020.html http • CWE-20: Improper Input Validation CWE-732: Incorrect Permission Assignment for Critical Resource •
