| Severity: | ||
| CVE ID: | ||
| Rule Protection Details |
|---|
| Description: | typecho 1.1/17.10.30 was discovered to contain a remote code execution (RCE) vulnerability via install.php. The vulnerability is caused by the install.php file that exits without processing after the error is caught, resulting in a bypass, and the value of the __typecho_config parameter is deserialized when the subsequent operation of install.php is executed, resulting in a medium and remote Code execution (RCE) vulnerability. This rule has the possibility of false positives and needs to be analyzed in combination with the value of the __typecho_config parameter of the specific hit traffic. | |
| Impact: | An attacker can carefully construct malicious serialized data and pass it to the application, and execute the malicious code constructed by the attacker when the application deserializes the object. | |
| Affected OS: | Windows, Linux, Others | |
