CVSS: 9.8EPSS: 26%CPEs: 8EXPL: 2CVE-2014-4650 – Python CGIHTTPServer - Encoded Directory Traversal
https://notcve.org/view.php?id=CVE-2014-4650
The CGIHTTPServer module in Python 2.7.5 and 3.3.4 does not properly handle URLs in which URL encoding is used for path separators, which allows remote attackers to read script source code or conduct directory traversal attacks and execute unintended code via a crafted character sequence, as demonstrated by a %2f separator. El módulo CGIHTTPServer en Python versiones 2.7.5 y 3.3.4, no maneja apropiadamente las URL en las que la codificación de URL es usada para los separadores de ruta, lo que permite a atacantes remotos leer el código fuente del script o conducir un salto de directorio y ejecutar código no deseado por medio de una secuencia de caracteres diseñada, como es demostrado mediante un separador %2f. It was discovered that the CGIHTTPServer module incorrectly handled URL encoded paths. A remote attacker could use this flaw to execute scripts outside of the cgi-bin directory, or disclose source of scripts in the cgi-bin directory. • https://www.exploit-db.com/exploits/33894 http://bugs.python.org/issue21766 http://openwall.com/lists/oss-security/2014/06/26/3 https://access.redhat.com/security/cve/cve-2014-4650 https://access.redhat.com/security/cve/CVE-2014-4650 https://bugzilla.redhat.com/show_bug.cgi?id=1113527 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-138: Improper Neutralization of Special Elements •

https://notcve.org/view.php?id=CVE-2014-0224
OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake, aka the "CCS Injection" vulnerability. OpenSSL anterior a 0.9.8za, 1.0.0 anterior a 1.0.0m y 1.0.1 anterior a 1.0.1h no restringe debidamente el procesamiento de mensajes ChangeCipherSpec, lo que permite a atacantes man-in-the-middle provocar el uso de una clave maestra de longitud cero en ciertas comunicaciones OpenSSL-a-OpenSSL, y como consecuencia secuestrar sesiones u obtener información sensible, a través de una negociación TLS manipulada, también conocido como la vulnerabilidad de 'inyección CCS'. It was found that OpenSSL clients and servers could be forced, via a specially crafted handshake packet, to use weak keying material for communication. A man-in-the-middle attacker could use this flaw to decrypt and modify traffic between a client and a server. • https://github.com/secretnonempty/CVE-2014-0224 https://github.com/iph0n3/CVE-2014-0224 http://aix.software.ibm.com/aix/efixes/security/openssl_advisory9.asc http://ccsinjection.lepidum.co.jp http://dev.mysql.com/doc/relnotes/workbench/en/wb-news-6-1-7.html http://esupport.trendmicro.com/solution/en-US/1103813.aspx http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10629 http://kb.juniper.net/InfoCenter/index?page=content&id=KB29195 http://kb.juniper.net/InfoCenter/ • CWE-326: Inadequate Encryption Strength CWE-841: Improper Enforcement of Behavioral Workflow •

https://notcve.org/view.php?id=CVE-2013-7040
Python 2.7 before 3.4 only uses the last eight bits of the prefix to randomize hash values, which causes it to compute hash values without restricting the ability to trigger hash collisions predictably and makes it easier for context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-1150. Python 2.7 anterior a 3.4 solamente utiliza las últimas ocho partes del prefijo para asignar valores de hash de forma aleatoria, lo que causa que calcule valores de hash sin restringir la habilidad de provocar colisiones de hash de forma previsible y facilita a atacantes dependientes de contexto causar una denegación de servicio (consumo de CPU) a través de entradas manipuladas hacia una aplicación que mantiene una tabla de hash. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2012-1150. • http://bugs.python.org/issue14621 http://lists.apple.com/archives/security-announce/2015/Aug/msg00001.html http://www.openwall.com/lists/oss-security/2013/12/09/13 http://www.openwall.com/lists/oss-security/2013/12/09/3 http://www.securityfocus.com/bid/64194 https://support.apple.com/kb/HT205031 • CWE-310: Cryptographic Issues •

Buffer overflow in the socket.recvfrom_into function in Modules/socketmodule.c in Python 2.5 before 2.7.7, 3.x before 3.3.4, and 3.4.x before 3.4rc1 allows remote attackers to execute arbitrary code via a crafted string. Desbordamiento de buffer en la función socket.recvfrom_into en Modules/socketmodule.c en Python 2.5 anterior a 2.7.7, 3.x anterior a 3.3.4 y 3.4.x anterior a 3.4rc1 permite a atacantes remotos ejecutar código arbitrario a través de una cadena manipulada. It was discovered that the socket.recvfrom_into() function failed to check the size of the supplied buffer. This could lead to a buffer overflow when the function was called with an insufficiently sized buffer. • https://www.exploit-db.com/exploits/31875 http://bugs.python.org/issue20246 http://hg.python.org/cpython/rev/87673659d8f7 http://lists.apple.com/archives/security-announce/2015/Aug/msg00001.html http://lists.opensuse.org/opensuse-updates/2014-04/msg00035.html http://lists.opensuse.org/opensuse-updates/2014-05/msg00008.html http://pastebin.com/raw.php?i=GHXSmNEg http://rhn.redhat.com/errata/RHSA-2015-1064.html http://rhn.redhat.com/errata/RHSA-2015-1330.html http://www&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

Algorithmic complexity vulnerability in the ssl.match_hostname function in Python 3.2.x, 3.3.x, and earlier, and unspecified versions of python-backports-ssl_match_hostname as used for older Python versions, allows remote attackers to cause a denial of service (CPU consumption) via multiple wildcard characters in the common name in a certificate. Vulnerabilidad de la complejidad algorítmica en la función ssl.match_hostname en Python 3.2.x, 3.3.x, y anteriores, y las versiones no especificadas de python-backports-ssl_match_hostname como las usadas por versiones anteriores de Python, permite a atacantes remotos provocar una denegación de servicio (consumo de CPU ) a través de múltiples caracteres comodín en el nombre común en el certificado. A denial of service flaw was found in the way Python's SSL module implementation performed matching of certain certificate names. A remote attacker able to obtain a valid certificate that contained multiple wildcard characters could use this flaw to issue a request to validate such a certificate, resulting in excessive consumption of CPU. • http://bugs.python.org/issue17980 http://rhn.redhat.com/errata/RHSA-2014-1690.html http://secunia.com/advisories/55107 http://secunia.com/advisories/55116 http://www.openwall.com/lists/oss-security/2013/05/16/6 http://www.ubuntu.com/usn/USN-1983-1 http://www.ubuntu.com/usn/USN-1984-1 http://www.ubuntu.com/usn/USN-1985-1 https://access.redhat.com/errata/RHSA-2016:1166 https://bugzilla.redhat.com/show_bug.cgi?id=963260 https://access.redhat.com/ • CWE-399: Resource Management Errors CWE-407: Inefficient Algorithmic Complexity •
