Recently, webarx researchers announced two high-risk authentication bypass vulnerabilities in WordPress plug-ins, which allow attackers to log in to an administrator account without a password.
The two plug-ins are infinitewp client and WP time capsule. It is designed to help users manage an unlimited number of WordPress websites from a central server and do backup management.
According to the report released by WebARX, the InfiniteWP Client plug-in is valid on more than 300000 websites, and the WP Time Capsule plug-in is valid on more than 20000 websites. The exploit process of the infinitewp client plug-in is simple, and CVss score is 9.8.
WebARX also points out that since authentication bypass vulnerabilities are usually logical errors in code and do not actually involve payloads that appear suspicious, it is difficult to use common firewall rules to prevent such vulnerabilities in this case.
Fortunately, plug-in developers have released a new version of the fix the next day after the vulnerability was submitted. It is recommended that users update it in time.
- InfiniteWP Client Version < 184.108.40.206
- WP Time Capsule Version < 1.21.16
- InfiniteWP Client Version = 220.127.116.11
- WP Time Capsule Version = 1.21.16
A new version that fixes the above vulnerability has been released. It is recommended that the affected users upgrade and update to prevent risks. The update download page is as follows.
