Privilege escalation flaw identified in the Jupiter and JupiterX Core Plugin affects much more than 90,000 web-sites.
A critical privilege escalation flaw uncovered in two themes utilised by far more than 90,000 WordPress websites can allow threat actors to just take above the websites completely, scientists have located.
WordFence Menace Intelligence Staff researcher Ramuel Gall found out the flaw, a single of five vulnerabilities he uncovered between early April and early Could in the Jupiter and JupiterX High quality WordPress themes, he discovered in a website article released Wednesday.
1 of the flaws—tracked as CVE-2022-1654 and rated as 9.9, or critical on the CVSS–allows for “any authenticated attacker, such as a subscriber or customer-degree attacker, to get administrative privileges and entirely take about any web-site jogging both the Jupiter Theme or JupiterX Core Plugin,” he wrote. The plugin is required to run the JupiterX topic.
Afflicted versions of the themes are: Jupiter Theme 6.10.1 or previously, and JupiterX Main Plugin 2..7 or earlier.
WordFence finished their investigation of most of flaws on April 5 and noted them to the Jupiter and JupiterX topic developer ArtBees on the similar working day on May possibly 3 they notified the developer of an further Jupiter theme flaw. By May possibly 10, the developed experienced produced up-to-date versions of both of those the Jupiter and JupiterX themes that had patched all the flaws.
Critical Vulnerability
The critical flaw uncovered resides in a operate, uninstallTemplate, which is meant to reset a web-site just after a template is uninstalled. However, it “has the supplemental influence of elevating the user contacting the operate to an administrator purpose,” Gall wrote. In the Jupiter theme, the perform is identified in the concept itself in JupiterX, it’s present in the JupiterX Core plugin.
“Vulnerable variations sign up AJAX steps but do not accomplish any capability checks or nonce checks,” he wrote.
On a internet site with a vulnerable variation of the Jupiter Topic installed, any logged-in person can elevate their privileges to all those of an administrator by sending an AJAX ask for with the motion parameter set to abb_uninstall_template. This phone calls the uninstallTemplate purpose, which phone calls the resetWordpressDatabase functionality, which proficiently reinstalls the web site with the presently logged-in person as the new site owner, Gall explained.
On a web page the place a vulnerable version of the JupiterX Core plugin is mounted, an individual can entry the identical functionality by sending an AJAX ask for with the motion parameter established to jupiterx_core_cp_uninstall_template, he said.
Other Vulnerabilities
WordPress plugins, generally designed by third-celebration builders, are notoriously buggy. Earlier flaws found in plugins for the well known website-development and -hosting system also have permitted for web site takeover, as well as enabled WordPress subscribers to entirely wipe sites not belonging to them, or attackers to forge email messages to subscribers.
Of the other flaws that Gall identified, three—tracked as CVE-2022-1656, CVE-2022-1658 and CVE-2022-1659–are rated as medium risk and one, CVE-2022-1657 is rated as significant risk.
The significant-risk flaw, which impacts JupiterX Theme 2..6 or previously and Jupiter Theme 6.10.1 or before, can enable an attacker to receive privileged information and facts, this sort of as nonce values, or execute restricted actions, Gall explained. This can be carried out by which include and executing information from any site on the web page.
“Vulnerable variations of the Jupiter and JupiterX Themes make it possible for logged-in consumers, which includes subscriber-degree buyers, to conduct Path Traversal and Area File inclusion,” Gall discussed.
In the JupiterX topic, this can be performed by using the jupiterx_cp_load_pane_action AJAX action existing in the lib/admin/handle-panel/manage-panel.php file to call the load_manage_panel_pane purpose. “It is probable to use this action to include any nearby PHP file by way of the slug parameter,” Gall wrote.
The Jupiter topic has a almost equivalent vulnerability, which an attacker can exploit by way of the mka_cp_load_pane_action AJAX action current in the framework/admin/handle-panel/logic/features.php file, which phone calls the mka_cp_load_pane_action perform, he explained.
Wordfence researchers advocate that anybody employing the impacted themes up-to-date to the patched versions quickly. The business released a firewall rule to secure Wordfence Premium, Wordfence Treatment and Wordfence Reaction buyers on April 5, and free Wordfence buyers on May 4.
