Q1What is this vulnerability? (Essence + Consequences)
๐ ๏ธ **Root Cause**: Improper access control in the auto-completion plugin. ๐ **Flaw**: The plugin exposes XML files (e.g., `domain/en.xml`) that store autocomplete history without authentication.โฆ
๐ฏ **Affected**: Ametys CMS versions **before 4.5.0**. ๐ฆ **Component**: The `auto-completion` plugin specifically. ๐ **Scope**: Any instance running these older versions is vulnerable.
Q4What can hackers do? (Privileges/Data)
๐ต๏ธ **Hackers Can**: Read autocomplete XML files remotely. ๐ **Data Accessed**: All typed characters, including content from **private pages**.โฆ
โก **Threshold**: **LOW**. ๐ช **Auth**: None required (Remote Unauthenticated). โ๏ธ **Config**: Exploits the default behavior of the auto-completion plugin. ๐ฏ **Ease**: Simple HTTP request to specific paths.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exp**: **YES**. ๐ **PoC**: Python script by `p0dalirius` dumps data to SQLite. ๐งช **Scanner**: Nuclei templates available for detection. ๐ **Status**: Actively exploitable in the wild.
Q7How to self-check? (Features/Scanning)
๐ **Check**: Request paths like `/plugins/web/service/search/auto-completion/domain/en.xml`. ๐ก **Scan**: Use Nuclei templates (`CVE-2022-26159.yaml`). ๐ **Verify**: Look for XML responses containing user input data.
