"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.
- In Joomla! before 3.9.19, lack of input validation in
the heading tag option of the Articles - Newsflash and
Articles - Categories modules allows XSS.
(CVE-2020-13761)
- In Joomla! before 3.9.19, the default settings of the
global textfilter configuration do not block HTML inputs
for Guest users. (CVE-2020-13763)
- In Joomla! before 3.9.19, incorrect input validation of
the module tag option in com_modules allows XSS.
(CVE-2020-13762)
- In jQuery versions greater than or equal to 1.2 and
before 3.5.0, passing HTML from untrusted sources - even
after sanitizing it - to one of jQuery's DOM
manipulation methods (i.e. .html(), .append(), and
others) may execute untrusted code. This problem is
patched in jQuery 3.5.0. (CVE-2020-11022)
- In jQuery versions greater than or equal to 1.0.3 and
before 3.5.0, passing HTML containing elements
from untrusted sources - even after sanitizing it - to
one of jQuery's DOM manipulation methods (i.e. .html(),
.append(), and others) may execute untrusted code. This
problem is patched in jQuery 3.5.0. (CVE-2020-11023)
- In Joomla! before 3.9.19, missing token checks in
com_postinstall lead to CSRF. (CVE-2020-13760)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
