Tpshop · Tp-Shop · CVE-2018-9919
**Name of the Vulnerable Software and Affected Versions**
Tp-shop versions 2.0.5 through 2.0.8
**Description**
A web-accessible backdoor exists, allowing remote attackers to obtain sensitive information, attack intranet hosts, or possibly trigger remote command execution. This issue is related to the `/vendor/phpdocumentor/reflection-docblock/tests/phpDocumentor/Reflection/DocBlock/Tag/LinkTagTeet.php` endpoint, which writes data from the `down url` URL into the `bddlj` local file if the attacker knows the backdoor `jmmy` parameter.
**Recommendations**
For Tp-shop versions 2.0.5 through 2.0.8, consider restricting access to the `/vendor/phpdocumentor/reflection-docblock/tests/phpDocumentor/Reflection/DocBlock/Tag/LinkTagTeet.php` endpoint to minimize the risk of exploitation. Avoid using the `jmmy` parameter in the affected endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
