Amazon Linux 2 : php (ALASPHP8.2-2024-004)

medium Nessus Plugin ID 198260

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of php installed on the remote host is prior to 8.2.19-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2PHP8.2-2024-004 advisory.

 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). (CVE-2024-2756)

 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. (CVE-2024-3096)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update php' to update your system.
