A deserialization flaw was discovered in Apache Tomcat's use of a FileStore. An attacker can exploit the flaw if all of the following are true: An attacker is able to control the contents and name of a file on the server. The server is configured to use the PersistenceManager with a FileStore. The PersistenceManager is configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker-provided object to be deserialized. The attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over. If all these conditions are true, the attacker can use a specifically crafted request to trigger Remote Code Execution through deserialization of the file under their control.

This flaw affects the following Tomcat versions: 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54, and 7.0.0 to 7.0.103.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Oracle ADF Faces. Authentication is not required to exploit this vulnerability. The specific flaw exists within the Remote Regions component. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the web server.

Vulnerability in the Oracle Communications Diameter Signaling Router (DSR) product of Oracle Communications (component: User Interface). Supported versions that are affected are 8.0.0.0-8.4.0.5. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Communications Diameter Signaling Router (DSR). Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Communications Diameter Signaling Router (DSR), attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Communications Diameter Signaling Router (DSR) accessible data as well as unauthorized read access to a subset of Oracle Communications Diameter Signaling Router (DSR) accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N).
