[原文]FlatNuke 2.5.5 and possibly earlier versions allows remote attackers to obtain sensitive information via (1) a null byte or (2) an MS-DOS device name such as AUX, CON, PRN, COM1, or LPT1 in the mod parameter.
FlatNuke contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when a remote attacker provides malformed input to the 'mod' variable in the 'index.php' script, which will disclose the software's installation path resulting in a loss of confidentiality. While such information is relatively low risk, it is often useful in carrying out additional, more focused attacks.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
