Joomla! 2.5.x < 3.9.19 Multiple Vulnerabilities

According to its self-reported version, the instance of Joomla! running on the remote web server is 2.5.x prior to 3.9.19. It is, therefore, affected by multiple vulnerabilities :

• Lack of input validation in the heading tag option of the "Articles – Newsflash" and "Articles - Categories" modules allow Cross-Site Scripting (XSS) attacks. (CVE-2020-13761)

• The default settings of the global textfilter configuration doesn’t block HTML inputs for Guest users. (CVE-2020-13763)

• Incorrect input validation of the module tag option in com_modules allow Cross-Site Scripting (XSS) attacks. (CVE-2020-13762)

• Two Cross-Site Scripting (XSS) vulnerabilities in jQuery. (CVE-2020-11022 / CVE-2020-11023)

• Missing token checks in com_postinstall cause CSRF vulnerabilities. (CVE-2020-13760)

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