IBM Cognos Analytics 11.2.0, 11.2.4, 12.0, and 12.1.0 and IBM Cognos Transformer 11.2.4, 12.0, and 12.1.0 are vulnerable to cross-site scripting (XSS). This vulnerability allows a remote attacker to inject arbitrary JavaScript code into the web user interface, which may alter the intended functionality and could lead to the disclosure of credentials within a trusted session.

IBM Cognos Analytics 11.2.0, 12.0, and 12.1.0 and IBM Cognos Transformer 12.0, 11.2.4, and 12.1.0 is vulnerable to stored cross-site scripting (XSS) in Cognos Adminstration. This vulnerability allows a privileged user to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.

Impact

On Windows, the shared %PROGRAMDATA% directory is searched for configuration files (SYSTEMCONFIGPATH and SYSTEMJUPYTERPATH), which may allow users to create configuration files affecting other users.

Only shared Windows systems with multiple users and unprotected %PROGRAMDATA% are affected.

Mitigations

- upgrade to jupytercore>=5.8.1 (5.8.0 is patched but breaks jupyter-server) , or - as administrator, modify the permissions on the %PROGRAMDATA% directory so it is not writable by unauthorized users, or - as administrator, create the %PROGRAMDATA%\jupyter directory with appropriately restrictive permissions, or - as user or administrator, set the %PROGRAMDATA% environment variable to a directory with appropriately restrictive permissions (e.g. controlled by administrators or the current user)

IBM Semeru Runtime 8.0.302.0 through 8.0.442.0, 11.0.12.0 through 11.0.26.0, 17.0.0.0 through 17.0.14.0, and 21.0.0.0 through 12.0.6.0 is vulnerable to a denial of service caused by a buffer overflow and subsequent crash, due to a defect in its native AES/CBC encryption implementation.

In Eclipse OpenJ9 versions up to 0.51, when used with OpenJDK version 8 a stack based buffer overflow can be caused by modifying a file on disk that is read when the JVM starts.

An unspecified vulnerability in Java SE related to the Server: DDL component could allow a remote attacker to cause high confidentiality and high integrity impact.

corydolphin/flask-cors version 4.01 contains a vulnerability where the request path matching is case-insensitive due to the use of the trymatch function, which is originally intended for matching hosts. This results in a mismatch because paths in URLs are case-sensitive, but the regex matching treats them as case-insensitive. This misconfiguration can lead to significant security vulnerabilities, allowing unauthorized origins to access paths meant to be restricted, resulting in data exposure and potential data leaks.
