(2) Vulnerability Details:
DLGuard web application has a computer security bug problem. It can be exploited by information leakage attacks – Full Path Disclosure (FPD). This may allow a remote attacker to disclose the software’s installation path. While such information is relatively low risk, it is often useful in carrying out additional, more focused attacks.
