OpencatsCVEs & Vulnerabilities

A stored cross-site scripting (XSS) vulnerability in OpenCATS v0.9.7 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the state parameter at opencats/index.php?m=candidates.

A stored cross-site scripting (XSS) vulnerability in OpenCATS v0.9.7 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the city parameter at opencats/index.php?m=candidates.

A Cross-Site Request Forgery (CSRF) in OpenCATS 0.9.7 allows attackers to force users into submitting web requests via unspecified vectors.

Cross-site request forgery is facilitated by OpenCATS failure to require CSRF tokens in POST requests. An attacker can exploit this issue by creating a dummy page that executes Javascript in an authenticated user's session when visited.

Improper neutralization of input during web page generation allows an authenticated attacker with access to a restricted account to submit malicious Javascript as the description for a calendar event, which would then be executed in other users' browsers if they browse to that event. This could result in stealing session tokens from users with higher permission levels or forcing users to make actions without their knowledge.

Improper neutralization of input during web page generation allows an unauthenticated attacker to submit malicious Javascript as the answer to a questionnaire which would then be executed when an authenticated user reviews the candidate's submission. This could be used to steal other users’ cookies and force users to make actions without their knowledge.

An open redirect vulnerability exposes OpenCATS to template injection due to improper validation of user-supplied GET parameters.

Opencats v0.9.7 was discovered to contain a stored cross-site scripting (XSS) vulnerability in the component /opencats/index.php?m=calendar. This vulnerability allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the Description or Title text fields.

Opencats v0.9.7 was discovered to contain a reflected cross-site scripting (XSS) vulnerability via the component /opencats/index.php?m=settings&a=ajax_tags_upd.

Opencats v0.9.7 was discovered to contain a SQL injection vulnerability via the importID parameter in the Import viewerrors function.

OpenCATS v0.9.6 was discovered to contain a SQL injection vulnerability via the importID parameter in the Import viewerrors function.

OpenCATS v0.9.6 was discovered to contain a SQL injection vulnerability via the tag_id variable in the Tag deletion function.

OpenCATS v0.9.6 was discovered to contain a SQL injection vulnerability via the entriesPerPage variable.

OpenCATS v0.9.6 was discovered to contain a SQL injection vulnerability via the tag_id variable in the Tag update function.

OpenCATS v0.9.6 was discovered to contain a remote code execution (RCE) vulnerability via the getDataGridPager's ajax functionality.

OpenCATS v0.9.6 was discovered to contain a reflected cross-site scripting (XSS) vulnerability via the email parameter in the Check Email function.

OpenCATS v0.9.6 was discovered to contain a reflected cross-site scripting (XSS) vulnerability via the indexFile component.

OpenCATS v0.9.6 was discovered to contain a reflected cross-site scripting (XSS) vulnerability via the callback component.

OpenCATS v0.9.6 was discovered to contain a reflected cross-site scripting (XSS) vulnerability via the entriesPerPage parameter.

OpenCATS v0.9.6 was discovered to contain a reflected cross-site scripting (XSS) vulnerability via the joborderID parameter.

OpenCATS through 0.9.6 allows remote attackers to execute arbitrary code by uploading an executable file via lib/FileUtility.php.

OpenCATS through 0.9.5-3 has multiple Cross-site Scripting (XSS) issues.

OpenCATS through 0.9.5-3 unsafely deserializes index.php?m=activity requests, leading to remote code execution. This occurs because lib/DataGrid.php calls unserialize for the parametersactivity:ActivityDataGrid parameter. The PHP object injection exploit chain can leverage an __destruct magic method in guzzlehttp.

lib/DocumentToText.php in OpenCats before 0.9.4-3 has XXE that allows remote users to read files on the underlying operating system. The attacker must upload a file in the docx or odt format.
