IBM WebSphere Portal 7.0, 8.0, 8.5, and 9.0 may fail to set the correct user context in certain impersonation scenarios, which can allow a user to act with the identity of a different user. IBM X-Force ID: 144958.

IBM Rational Engineering Lifecycle Manager 5.0 through 5.02 and 6.0 through 6.0.6 could allow remote attackers to bypass authentication via a direct request or forced browsing to a page other than URL intended. IBM X-Force ID: 142561.

IBM API Connect 5.0.0.0-5.0.8.3 Developer Portal does not enforce Two Factor Authentication (TFA) while resetting a user password but enforces it for all other login scenarios. IBM X-Force ID: 144483.

An XML parsing vulnerability affects IBM SAML-based single sign-on (SSO) systems (IBM Security Access Manager 9.0.0 - 9.0.4 and IBM Tivoli Federated Identity Manager 6.2 - 6.0.2.) This vulnerability can allow an attacker with authenticated access to trick SAML systems into authenticating as a different user without knowledge of the victim users password. IBM X-Force ID: 139754.

IBM Spectrum Copy Data Management 2.2.13 and earlier has weak authentication and password rules and incorrectly handles default credentials for the Spectrum Copy Data Management Admin console. IBM X-Force ID: 214957.

In Enterprise Networking Operating System (ENOS) in Lenovo and IBM RackSwitch and BladeCenter products, an authentication bypass known as "HP Backdoor" was discovered during a Lenovo security audit in the serial console, Telnet, SSH, and Web interfaces. This bypass mechanism can be accessed when performing local authentication under specific circumstances. If exploited, admin-level access to the switch is granted.

IBM DB2 9.7, 10,1, 10.5, and 11.1 is vulnerable to an unauthorized command that allows the database to be activated when authentication type is CLIENT. IBM X-Force ID: 129830.

IDSWebApp in the Web Administration Tool in IBM Tivoli Directory Server (TDS) 6.2 before 6.2.0.3-TIV-ITDS-IF0004 does not require authentication for access to LDAP Server log files, which allows remote attackers to obtain sensitive information via a crafted URL.

IBM WebSphere Application Server (WAS) Liberty Profile 8.5 before 8.5.0.2, when SSL is not enabled, does not properly validate authentication cookies, which allows remote authenticated users to bypass intended access restrictions via an HTTP session.

IBM Connect:Direct for UNIX 6.1.0, 6.0.0, 4.3.0, and 4.2.0 can allow a local or remote user to obtain an authenticated CLI session due to improper authentication methods. IBM X-Force ID: 188516.

IBM Spectrum Protect Client 8.1.7.0 through 8.1.9.1 (Linux and Windows), 8.1.9.0 trough 8.1.9.1 (AIX) and IBM Spectrum Protect for Space Management 8.1.7.0 through 8.1.9.1 (Linux), 8.1.9.0 through 8.1.9.1 (AIX) web user interfaces could allow an attacker to bypass authentication due to improper session validation which can result in access to unauthorized resources. IBM X-Force ID: 182019.

IBM Event Streams 10.0.0 could allow an authenticated user to perform tasks to a schema due to improper authentication validation. IBM X-Force ID: 186233.

IBM Security Guardium Insights 2.0.1 could allow an attacker to obtain sensitive information or perform unauthorized actions due to improper authenciation mechanisms. IBM X-Force ID: 174403.

The (1) CHAP and (2) MS-CHAP-V2 authentication capabilities in the PPP Access Concentrator (PPPAC) function in Internet Initiative Japan SEIL/B1 firmware 1.00 through 2.52 use the same challenge for each authentication attempt, which allows remote attackers to bypass authentication via a replay attack.

The CMS_verify function in OpenSSL 0.9.8h through 0.9.8j, when CMS is enabled, does not properly handle errors associated with malformed signed attributes, which allows remote attackers to repudiate a signature that originally appeared to be valid but was actually invalid.

The rsaauth extension in TYPO3 4.3.0 through 4.3.14, 4.4.0 through 4.4.15, 4.5.0 through 4.5.39, and 4.6.0 through 4.6.18, when configured for the frontend, allows remote attackers to bypass authentication via a password that is casted to an empty value.

A vulnerability classified as critical has been found in Comodo Internet Security Premium 12.3.4.8162. This affects an unknown part of the component Update Handler. The manipulation leads to improper certificate validation. It is possible to initiate the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. The vendor was contacted early about this disclosure but did not respond in any way.

A vulnerability, which was classified as problematic, has been found in YXJ2018 SpringBoot-Vue-OnlineExam 1.0. This issue affects some unknown processing of the component API. The manipulation leads to improper authentication. The attack may be initiated remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used.

Python-apt doesn't check if hashes are signed in `Version.fetch_binary()` and `Version.fetch_source()` of apt/package.py or in `_fetch_archives()` of apt/cache.py in version 1.9.3ubuntu2 and earlier. This allows downloads from unsigned repositories which shouldn't be allowed and has been fixed in verisions 1.9.5, 1.9.0ubuntu1.2, 1.6.5ubuntu0.1, 1.1.0~beta1ubuntu0.16.04.7, 0.9.3.5ubuntu3+esm2, and 0.8.3ubuntu7.5.
