Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Leverage Executable Code in Non-Executable Files An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
- Manipulating User-Controlled Variables This attack targets user controlled variables (DEBUG=1, PHP Globals, and So Forth). An attacker can override environment variables leveraging user-supplied, untrusted query variables directly used on the application server without any data sanitization. In extreme cases, the attacker can change variables controlling the business logic of the application. For instance, in languages like PHP, a number of poorly set default configurations may allow the user to override variables.

NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2005-138.NASL description Updated postresql packages that correct various security issues are now available for Red Hat Enterprise Linux 4. This update has been rated as having important security impact by the Red Hat Security Response Team. A flaw in the LOAD command in PostgreSQL was discovered. A local user could use this flaw to load arbitrary shared libraries and therefore execute arbitrary code, gaining the privileges of the PostgreSQL server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-0227 to this issue. A permission checking flaw in PostgreSQL was discovered. A local user could bypass the EXECUTE permission check for functions by using the CREATE AGGREGATE command. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-0244 to this issue. Multiple buffer overflows were found in PL/PgSQL. A database user who has permissions to create plpgsql functions could trigger this flaw which could lead to arbitrary code execution, gaining the privileges of the PostgreSQL server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2005-0245 and CVE-2005-0247 to these issues. A flaw in the integer aggregator (intagg) contrib module for PostgreSQL was found. A user could create carefully crafted arrays and cause a denial of service (crash). The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-0246 to this issue. The update also fixes some minor problems, notably conflicts with SELinux. Users of postgresql should update to these erratum packages that contain patches and are not vulnerable to these issues. last seen 2020-06-01 modified 2020-06-02 plugin id 17192 published 2005-02-22 reporter This script is Copyright (C) 2005-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/17192 title RHEL 4 : postgresql (RHSA-2005:138) NASL family Debian Local Security Checks NASL id DEBIAN_DSA-668.NASL description John Heasman and others discovered a bug in the PostgreSQL engine which would allow any user load an arbitrary local library into it. last seen 2020-06-01 modified 2020-06-02 plugin id 16342 published 2005-02-10 reporter This script is Copyright (C) 2005-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/16342 title Debian DSA-668-1 : postgresql - privilege escalation NASL family FreeBSD Local Security Checks NASL id FREEBSD_PKG_5D4251897A0311D9A9E70001020EED82.NASL description John Heasman and others disovered that non-privileged users could use the LOAD extension to load arbitrary libraries into the postgres server process space.
