Vulnerabilidades

org.gaul S3Proxy implements the S3 API and proxies requests. Users of the filesystem and filesystem-nio2 storage backends could unintentionally expose local files to users. This issue has been addressed in version 2.6.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.

webadmin.c in 3proxy before 0.8.13 has an out-of-bounds write in the admin interface.

Double free vulnerability in the ftpprchild function in ftppr in 3proxy 0.5 through 0.5.3i allows remote attackers to cause a denial of service (daemon crash) via multiple OPEN commands to the FTP proxy.

Buffer overflow in the HTTP proxy service for 3proxy 0.5 to 0.5.3g, and 0.6b-devel before 20070413, might allow remote attackers to execute arbitrary code via crafted transparent requests.

3proxy 0.5 to 0.5.2 does not offer NTLM authentication before basic authentication, which might cause browsers with incomplete RFC2616/RFC2617 support to use basic cleartext authentication even if NTLM is available, which makes it easier for attackers to steal credentials.

3proxy 0.5 to 0.5.2, when NT-encoded passwords are being used, allows remote attackers to cause a denial of service (blocked account) via unspecified vectors related to NTLM authentication, which causes a password hash to be overwritten.
