Http Parameter Contamination

HTTP PARAMETER CONTAMINATION (HPC) original idea comes from the innovative approach found in HPP research by exploring deeper and exploiting strange behaviors in Web Server components, Web Applications and Browsers as a result of query string parameter contamination with reserved or non expected characters.

Real world examples: Bypass Mod_Security SQL Injection rule, Bypass URLScan 3.1 DenyQueryStringSequences rule

dotCMS Multiple Cross-Site Scripting Vulnerabilities

(CVE-2013-3484) dotCMS is prone to multiple cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input. An attacker may leverage these issues to execute arbitrary HTML and script code in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks.

Symantec Endpoint Protection Manager Cross-Site Request Forgery and Cross-Site Scripting

(SYM12-001, CVE-2011-0550, CVE-2011-0551) Symantec Endpoint Protection Manager 12.1 web console is susceptible to cross-site scripting and cross-site request forgery that could potentially lead to arbitrary code execution.

IT Dashboard "value" Cross-Site Scripting Vulnerability

(SA44033) Ivan Markovic has discovered a vulnerability in IT Dashboard, which can be exploited by malicious people to conduct cross-site scripting attacks

UltraVNC Viewer Insecure Library Loading Vulnerability

(SA41208) The vulnerability is caused due to the UltraVNC Viewer loading libraries (e.g. vnclang.dll) in an insecure manner. This can be exploited to load arbitrary libraries by tricking a user into e.g. opening a VNC file located on a remote WebDAV or SMB share.

Axon Virtual PBX Multiple Vulnerabilities

(SA39098) Some vulnerabilities have been discovered in Axon Virtual PBX, which can be exploited by malicious users to manipulate certain data or disclose sensitive information and by malicious people to conduct cross-site scripting and cross-site request forgery attacks.

Elastix "id_nodo" Local File Inclusion Vulnerability

(CVE-2010-1492) Elastix is prone to a local file-include vulnerability because it fails to properly sanitize user-supplied input. An attacker can exploit this vulnerability to obtain potentially sensitive information or to execute arbitrary local scripts in the context of the webserver process. This may allow the attacker to compromise the application and the computer; other attacks are also possible.

Huawei HG510 Security Bypass and Cross-Site Request Forgery Vulnerabilities

(EDB-ID: 33648) Huawei HG510 is prone to multiple cross-site request-forgery vulnerabilities. Successful exploits may allow attackers to run privileged commands on the affected device, change configuration, cause denial-of-service conditions, or inject arbitrary script code. Other attacks are also possible.

Exponent CMS Multiple Vulnerabilities

(SA36703) Some vulnerabilities and a security issue have been discovered in Exponent CMS, which can be exploited by malicious users to compromise a vulnerable system and by malicious people to conduct cross-site scripting, SQL injection attacks and disclose system information

ESET Remote Administrator Script Insertion Vulnerability

(CVE-2009-0548) Input passed to the "ESET Administrator Additional Report Settings" interface is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in another user's context when the malicious report is viewed. Successful exploitation requires administrative user access.

Vivvo CMS "404 Page Not Found" Cross-Site Scripting Vulnerability

(CVE-2009-0466) Vivvo is prone to a cross-site scripting vulnerability because it fails to properly sanitize user-supplied input.  An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and to launch other attacks.

Kerio MailServer WebMail Cross-Site Scripting Vulnerabilities

(CVE-2008-5760) Kerio MailServer is prone to multiple cross-site scripting vulnerabilities because it fails to sufficiently sanitize user-supplied data. An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and to launch other attacks.

SquirrelMail Malformed HTML Mail Message Script Insertion

(CVE-2008-2379) A cross-site scripting (XSS) vulnerability was discovered in SquirrelMail web interface, which allows to inject arbitrary web script or HTML via a crafted hyperlink in an HTML part of an e-mail message. This can be triggered when viewing a malicious email message in HTML mode.

Link CMS Cross-Site Scripting and SQL Injection

(CVE-2006-6387) Link CMS is prone to multiple input-validation vulnerabilities, including SQL-injection issues and a cross-site scripting issue, because it fails to sufficiently sanitize user-supplied data. Exploiting these issues could allow an attacker to steal cookie-based authentication credentials, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database implementation.

emuCMS "query" and "page" Cross-Site Scripting Vulnerabilities

(CVE-2006-4822) emuCMS is prone to a cross-site scripting vulnerabilities because it fails to sufficiently sanitize user-supplied data. An attacker may leverage these issues to have arbitrary script code execute in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks.

vtiger CRM Multiple Vulnerabilities

(CVE-2006-4617, CVE-2006-4588, CVE-2006-4587) The vtiger CRM is prone to HTML-injection and access-control-bypass vulnerabilities because the application fails to properly sanitize user-supplied input and effectively control access to administrative modules.

SD Studio CMS SQL Injection Vulnerabilities

(CVE-2006-391) SD Studio CMS is prone to multiple input-validation vulnerabilities, including cross-site scripting and SQL-injection issues, because the application fails to properly sanitize user-supplied input.
A successful exploit of these vulnerabilities could allow an attacker to compromise the application, access or modify data, steal cookie-based authentication credentials, or even exploit vulnerabilities in the underlying database implementation. Other attacks are also possible.

sNews "search_query" Cross-Site Scripting Vulnerability

(CVE-2006-3916) Input passed to the "search_query" parameters in snews.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session.
