Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Deserialization of Untrusted Data (CVE-ID: CVE-2025-40551)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insecure input validation when processing serialized data. A remote non-authenticated attacker can send specially crafted data to the application and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Improper authentication (CVE-ID: CVE-2025-40552)

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in the authentication process. A remote non-authenticated attacker can bypass authentication process and gain unauthorized access to the application.


3) Deserialization of Untrusted Data (CVE-ID: CVE-2025-40553)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insecure input validation when processing serialized data. A remote non-authenticated attacker can pass specially crafted data to the application and execute arbitrary OS commands on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


4) Improper authentication (CVE-ID: CVE-2025-40554)

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in the authentication process. A remote non-authenticated attacker can bypass authentication process and gain unauthorized access to the application.


5) Improper access control (CVE-ID: CVE-2025-40536)

The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper access restrictions. A remote non-authenticated attacker can bypass implemented security restrictions and under certain circumstances gain unauthorized access to the application, leading to application compromise. 


6) Use of hard-coded credentials (CVE-ID: CVE-2025-40537)

The vulnerability allows a remote user to escalate privileges within the application.

The vulnerability exists due to presence of hard-coded credentials in application's code. A remote authenticated user can obtain credentials and gain administrative access to the application.
