GLSA-200710-21 : TikiWiki: Arbitrary command execution
High Nessus Plugin ID 27553
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200710-21 (TikiWiki: Arbitrary command execution)
ShAnKaR reported that input passed to the 'f' array parameter in tiki-graph_formula.php is not properly verified before being used to execute PHP functions.
An attacker could execute arbitrary code with the rights of the user running the web server by passing a specially crafted parameter string to the tiki-graph_formula.php file.
There is no known workaround at this time.
SolutionAll TikiWiki users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=www-apps/tikiwiki-188.8.131.52'
