Cross-site request forgery (CSRF) vulnerability in Opsview before 4.4.1 and Opsview Core before 20130522 allows remote attackers to hijack the authentication of administrators for requests that change the administrator password via unspecified vectors.

Multiple cross-site scripting (XSS) vulnerabilities in Opsview before 4.4.1 and Opsview Core before 20130522 allow remote attackers to inject arbitrary web script or HTML.

The test connection functionality in the NetAudit section of Opsview Monitor before 5.3.1 and 5.4.x before 5.4.2 is vulnerable to command injection due to improper sanitization of the rancid_password parameter.

The web management console of Opsview Monitor 5.4.x before 5.4.2 provides functionality accessible by an authenticated administrator to test notifications that are triggered under certain configurable events. The value parameter is not properly sanitized, leading to arbitrary command injection with the privileges of the nagios user account.

The diagnosticsb2ksy parameter of the /rest endpoint in Opsview Monitor before 5.3.1 and 5.4.x before 5.4.2 is vulnerable to Cross-Site Scripting.

The /etc/init.d/opsview-reporting-module script that runs at boot time in Opsview Monitor before 5.3.1 and 5.4.x before 5.4.2 invokes a file that can be edited by the nagios user, and would allow attackers to elevate their privileges to root after a system restart, hence obtaining full control of the appliance.

The data parameter of the /settings/api/router endpoint in Opsview Monitor before 5.3.1 and 5.4.x before 5.4.2 is vulnerable to Cross-Site Scripting.

In Opsview Monitor Pro (Prior to 5.1.0.162300841, prior to 5.0.2.27475, prior to 4.6.4.162391051, and 4.5.x without a certain 2016 security patch), an unauthenticated Directory Traversal vulnerability can be exploited by issuing a specially crafted HTTP GET request utilizing a simple URL encoding bypass, %252f instead of /.

Open redirect vulnerability in Opsview Monitor Pro (Prior to 5.1.0.162300841, prior to 5.0.2.27475, prior to 4.6.4.162391051, and 4.5.x without a certain 2016 security patch) allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via the back parameter to the /login URI.

Opsview before 2015-11-06 has XSS via SNMP.
