Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) XML External Entity injection (CVE-ID: CVE-2023-3823)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to insufficient validation of user-supplied XML input. A remote attacker can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.

Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.


2) Buffer overflow (CVE-ID: CVE-2023-3824)

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

The vulnerability exists due to a boundary error within the phar_dir_read() function. A remote attacker can force the application to open a specially crafted .phar archive,  trigger memory corruption and execute arbitrary code on the target system.


3) Security features bypass (CVE-ID: CVE-2024-2756)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to the way PHP handles HTTP variable names. A remote attacker can set a standard insecure cookie in the victim's browser which is treated as a `__Host-` or `__Secure-` cookie by PHP applications.

Note, the vulnerability exists due to incomplete fix for #VU67756 (CVE-2022-31629).


4) Improper Authentication (CVE-ID: CVE-2024-3096)

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in within the password_verify() function, which can erroneously return true. A remote attacker can bypass implemented authentication based on the vulnerable function and gain unauthorized access to the web application.
