wp-login.php in WordPress 2.8.3 and earlier allows remote attackers to force a password reset for the first user in the database, possibly the administrator, via a key[] array variable in a resetpass (aka rp) action, which bypasses a check that assumes that $key is not an array.

Event Monitor in Apple Mac OS X 10.5.8 does not properly handle crafted authentication data sent to an SSH daemon, which allows remote attackers to cause a denial of service via vectors involving processing of XML log documents by other services, related to a "log injection" issue.

RADIO istek scripti 2.5 stores sensitive information under the web root with insufficient access control, which allows remote attackers to obtain user credentials via a direct request for estafresgaftesantusyan.inc.

cups: improper use of the 'guest' username in the web UI, when user not logged on to the server

The web interface (cgi-bin/admin.c) in CUPS before 1.3.8 uses the guest username when a user is not logged on to the web server, which makes it easier for remote attackers to bypass intended policy and conduct CSRF attacks via the (1) add and (2) cancel RSS subscription functions.

Geert Moernaut LSrunasE 1.0 and Supercrypt 1.0 use the RC4 stream cipher without constructing a unique initialization vector (IV), which makes it easier for local users to obtain cleartext passwords.

The Sametime server in IBM Lotus Instant Messaging and Web Conferencing 6.5.1 generates error messages for a failed logon attempt with different time delays depending on whether the user account exists, which allows remote attackers to enumerate valid usernames.

Drupal 5.x before 5.19 and 6.x before 6.13 does not properly sanitize failed login attempts for pages that contain a sortable table, which includes the username and password in links that can be read from (1) the HTTP referer header of external web sites that are visited from those links or (2) when page caching is enabled, the Drupal page cache.

Armorlogic Profense Web Application Firewall before 2.2.22, and 2.4.x before 2.4.4, has a default root password hash, and permits password-based root logins over SSH, which makes it easier for remote attackers to obtain access.

Windows Mobile 6 on the HTC Hermes device makes WLAN passwords available to an auto-completion mechanism for the password input field, which allows physically proximate attackers to bypass password authentication and obtain WLAN access.

The password_check function in auth/auth_phpbb3.php in WoW Raid Manager 3.5.1 before Patch 1, when using PHPBB3 authentication, (1) does not invoke the CheckPassword function with the required arguments, which always triggers an authentication failure, and (2) returns true instead of false when an authentication failure occurs, which allows remote attackers to bypass authentication and gain privileges with an arbitrary password.

SmartFilter Web Gateway Security 4.2.1.00 stores user credentials in cleartext in admin_backup.xml files and uses insecure permissions for these files, which allows local users to gain privileges. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

Apple Safari before 4.0 does not properly check for revoked Extended Validation (EV) certificates, which makes it easier for remote attackers to trick a user into accepting an invalid certificate.

TekRADIUS 3.0 uses BUILTIN\Users:R permissions for the TekRADIUS.ini file, which allows local users to obtain obfuscated database credentials by reading this file.

The Internet Authentication Service (IAS) in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP2, Vista Gold and SP1, and Server 2008 Gold does not properly verify the credentials in an MS-CHAP v2 Protected Extensible Authentication Protocol (PEAP) authentication request, which allows remote attackers to access network resources via a malformed request, aka "MS-CHAP Authentication Bypass Vulnerability."

token.cgi in Bugzilla 3.4rc1 through 3.4.1 places a password in a URL at the beginning of a login session that occurs immediately after a password reset, which allows context-dependent attackers to discover passwords by reading (1) web-server access logs, (2) web-server Referer logs, or (3) the browser history.

The single sign-on implementation in Active Directory Federation Services (ADFS) in Microsoft Windows Server 2003 SP2 and Server 2008 Gold and SP2 does not properly remove credentials at the end of a network session, which allows physically proximate attackers to obtain the credentials of a previous user of the same web browser by using data from the browser's cache, aka "Single Sign On Spoofing in ADFS Vulnerability."

XAMPP installs multiple packages with insecure default passwords, which makes it easier for remote attackers to obtain access via (1) the "lampp" default password for the "nobody" account within the included ProFTPD installation, (2) a blank default password for the "root" account within the included MySQL installation, (3) a blank default password for the "pma" account within the phpMyAdmin installation, and possibly other unspecified passwords. NOTE: this was originally reported as a problem in DFLabs PTK, but this issue affects any product that is installed within the XAMPP environment, and should not be viewed as a vulnerability within that product. NOTE: DFLabs states that PTK is intended for use in a laboratory with "no contact from / to internet."

Textpattern (aka Txp CMS) 4.0.5 does not ask for the old password during a password reset, which makes it easier for remote attackers to change a password after hijacking a session.

Intellicom NetBiter WebSCADA devices use default passwords for the HICP network configuration service, which makes it easier for remote attackers to modify network settings and cause a denial of service. NOTE: this is only a vulnerability when the administrator does not follow recommendations in the product's installation documentation. NOTE: this issue was originally reported to be hard-coded passwords, not default passwords.

RioRey RIOS 4.6.6 and 4.7.0 uses an undocumented, hard-coded username (dbadmin) and password (sq!us3r) for an SSH tunnel, which allows remote attackers to gain privileges via port 8022.
