Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Catchpoint Systems WebPageTest has a critical flaw in `resultimage.php`. <br>π₯ **Consequences**: Attackers can upload arbitrary files, leading to **Remote Code Execution (RCE)**.β¦
π‘οΈ **Root Cause**: **CWE-434** (Unrestricted Upload of File with Dangerous Type). <br>π **Flaw**: The script fails to validate uploaded files. No checks on file type or content before saving.
Q3Who is affected? (Versions/Components)
π¦ **Affected**: **WebPageTest** by WPO Foundation. <br>π **Versions**: Version **2.6 and earlier**. If you are running an older open-source version, you are at risk.
Q4What can hackers do? (Privileges/Data)
π **Attacker Power**: Full **Remote Code Execution**. <br>π **Access**: Can upload malicious scripts (e.g., PHP shells) and execute them. Gain control over the server, steal data, or pivot to other systems.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: **LOW**. <br>π **Auth**: Typically requires no authentication for the upload endpoint in default configurations. <br>π **Config**: Direct access to the upload script allows immediate exploitation.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π₯ **Public Exploit**: **YES**. <br>π **Proof**: Exploit-DB IDs **19790** and **20173** exist. Metasploit module `webpagetest_upload_exec.rb` is available. Wild exploitation is highly likely.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for `resultimage.php` endpoints. <br>π§ͺ **Test**: Attempt to upload a non-image file (e.g., `.php` or `.jsp`). If the server accepts and stores it, you are vulnerable.β¦
π¨ **Urgency**: **CRITICAL**. <br>β±οΈ **Priority**: **IMMEDIATE ACTION**. <br>π **Risk**: High CVSS potential due to RCE and low exploitation barrier. Patch or mitigate within 24-48 hours.
