Joomla! < 3.7.0 Multiple Vulnerabilities

medium Nessus Plugin ID 99691

Synopsis

The remote web server contains a PHP application that is affected by multiple vulnerabilities.

Description

According to its self-reported version number, the Joomla! installation running on the remote web server is prior to 3.7.0. It is, therefore, affected by multiple vulnerabilities :

- A flaw exists in the JMail API due to PHPMail version information being included in mail headers. An unauthenticated, remote attacker can exploit this to disclose sensitive information. (CVE-2017-7983)

- A cross-site scripting (XSS) vulnerability exists in the template manager component due to improper validation of input before returning it to users. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2017-7984)

- A cross-site scripting (XSS) vulnerability exists in unspecified components when handling multibyte characters due to improper validation of input before returning it to users. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2017-7985)

- A cross-site scripting (XSS) vulnerability exists in unspecified components when handling certain HTML attributes due to improper validation of input before returning it to users. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2017-7986)

- A cross-site scripting (XSS) vulnerability exists in the template manager component due to inadequate escaping of file and folder name input before returning it to users.
An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2017-7987)

- A flaw exists due to improper sanitization of form content that allows an unauthenticated, remote attacker to overwrite the author of articles. (CVE-2017-7988)

- A flaw exists in MIME type checking that allows an authenticated, remote attacker with low privileges to upload SWF files even if this action is not allowed for the privilege level. (CVE-2017-7989)

- Multiple unspecified files exist that allow an unauthenticated, remote attacker to disclose the software's installation path on systems that have error reporting enabled. (CVE-2017-8057)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Joomla! version 3.7.0 or later.
