Multiple buffer overflows in Winamp Web Interface (Wawi) 7.5.13 and earlier (1) allow remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via an (a) long username or a (b) crafted packet to the FindBasicAuth function in security.cpp, related to the /browse URI; and allow remote authenticated users to cause a denial of service (application crash) and possibly execute arbitrary code via a long path string in the (2) Browse, (3) CControl::Download, and (4) CControl::Load functions, related to the file parameter in the /dl URI. NOTE: some of these details are obtained from third party information.

The CControl::Download function (/dl URI) in Winamp Web Interface (Wawi) 7.5.13 and earlier allows remote authenticated users to download arbitrary file types under the root via a trailing "." (dot) in a filename in the file parameter, related to erroneous behavior of the IsWinampFile function.

Directory traversal vulnerability in the Browse function (/browse URI) in Winamp Web Interface (Wawi) 7.5.13 and earlier allows remote authenticated users to list arbitrary directories via URL encoded backslashes ("%2F") in the path parameter.

Winamp Web Interface (Wawi) 7.5.13 and earlier uses an insufficient comparison to determine whether a directory is located below the application's root directory, which allows remote authenticated users to access certain other directories if the name of the root directory is a substring of the name of the target directory, as demonstrated by accessing C:\folder2 when the root directory is C:\folder.
