Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Server Side Include (SSI) Injection An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
- Cross Zone Scripting An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
- Cross Site Scripting through Log Files An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
- Command Line Execution through SQL Injection An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

Therefore, it may be affected by the following vulnerabilities : - A off-by-one overflow flaw exists within the SNMP processing component. By using a specially crafted UDP SNMP request, a remote attacker could exploit this to cause a denial of service or possibly execute arbitrary code. (CVE-2014-6270) - There exists an array indexing flaw in the node pinger that is triggered when parsing ICMP and ICMPv6 replies, which may allow a remote attacker to crash the pinger or obtain sensitive information.

Matthew Daley discovered that Squid 3 did not properly perform input validation in request parsing. A remote attacker could send crafted Range requests to cause a denial of service (CVE-2014-3609). Due to incorrect buffer management Squid can be caused by an attacker to write outside its allocated SNMP buffer (CVE-2014-6270). Due to incorrect bounds checking Squid pinger binary is vulnerable to denial of service or information leak attack when processing larger than normal ICMP or ICMPv6 packets (CVE-2014-7141). Due to incorrect input validation Squid pinger binary is vulnerable to denial of service or information leak attacks when processing ICMP or ICMPv6 packets (CVE-2014-7142). last seen 2020-06-01 modified 2020-06-02 plugin id 82356 published 2015-03-30 reporter This script is Copyright (C) 2015-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/82356 title Mandriva Linux Security Advisory : squid (MDVSA-2015:103) NASL family SuSE Local Security Checks NASL id SUSE_SU-2016-2089-1.NASL description This update for squid3 fixes the following issues : - Multiple issues in pinger ICMP processing.
