Name of the Vulnerable Software and Affected Versions
DBLTek devices (affected versions not specified)
Description
The issue allows remote attackers to execute arbitrary OS commands by obtaining the admin password via a "frame.html?content=/dev/mtdblock/5" request. The attacker can then use this password for HTTP Basic Authentication needed for a "change password.csp" request, which supports a "<%%25call system.exec:" string in the
passwd parameter. This vulnerability exists due to the lack of measures to neutralize special elements used in the operating system command.Recommendations
As a temporary workaround, consider disabling the
change password.csp script until a patch is available. Restrict access to the frame.html endpoint to minimize the risk of exploitation. Avoid using the passwd parameter in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
