UNKNOWN Summary
OpenAFS before 1.4.15, 1.6.x before 1.6.5, and 1.7.x before 1.7.26 uses weak encryption (DES) for Kerberos keys, which makes it easier for remote attackers to obtain the service key.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Signature Spoofing by Key Recreation An attacker obtains an authoritative or reputable signer's private signature key by exploiting a cryptographic weakness in the signature algorithm or pseudorandom number generation and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

NASL family Gentoo Local Security Checks NASL id GENTOO_GLSA-201404-05.NASL description The remote host is affected by the vulnerability described in GLSA-201404-05 (OpenAFS: Multiple vulnerabilities) Multiple vulnerabilities have been discovered in OpenAFS. Please review the CVE identifiers referenced below for details. Impact : An attacker could potentially execute arbitrary code with the permissions of the user running the AFS server, cause a Denial of Service condition, or gain access to sensitive information. Additionally, an attacker could compromise a cell’s private key, allowing them to impersonate any user in the cell. Workaround : There is no known workaround at this time. last seen 2020-06-01 modified 2020-06-02 plugin id 73394 published 2014-04-08 reporter This script is Copyright (C) 2014-2018 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/73394 title GLSA-201404-05 : OpenAFS: Multiple vulnerabilities code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Gentoo Linux Security Advisory GLSA 201404-05. # # The advisory text is Copyright (C) 2001-2016 Gentoo Foundation, Inc. # and licensed under the Creative Commons - Attribution / Share Alike # license.

Integer overflow in ptserver in OpenAFS before 1.6.2 allows remote attackers to cause a denial of service (crash) via a large list from the IdToName RPC, which triggers a heap-based buffer overflow (CVE-2013-1795). OpenAFS before 1.4.15, 1.6.x before 1.6.5, and 1.7.x before 1.7.26 uses weak encryption (DES) for Kerberos keys, which makes it easier for remote attackers to obtain the service key (CVE-2013-4134). The vos command in OpenAFS 1.6.x before 1.6.5, when using the -encrypt option, only enables integrity protection and sends data in cleartext, which allows remote attackers to obtain sensitive information by sniffing the network (CVE-2013-4135). Buffer overflow in the GetStatistics64 remote procedure call (RPC) in OpenAFS 1.4.8 before 1.6.7 allows remote attackers to cause a denial of service (crash) via a crafted statsVersion argument (CVE-2014-0159). A denial of service flaw was found in libxml2, a library providing support to read, modify and write XML and HTML files. A remote attacker could provide a specially crafted XML file that, when processed by an application using libxml2, would lead to excessive CPU consumption (denial of service) based on excessive entity substitutions, even if entity substitution was disabled, which is the parser default behavior (CVE-2014-3660). The updated packages have been upgraded to the 1.4.15 version and patched to correct these issues. last seen 2020-06-01 modified 2020-06-02 plugin id 79989 published 2014-12-15 reporter This script is Copyright (C) 2014-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/79989 title Mandriva Linux Security Advisory : openafs (MDVSA-2014:244) NASL family Scientific Linux Local Security Checks NASL id SL_20130724_OPENAFS_ON_SL5_X.NASL description OpenAFS uses Kerberos tickets to secure network traffic.
