Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly addresses the insufficient input validation in the Languages section by requiring validation mechanisms to block malicious payloads before CSV construction.
Filters output in generated CSV files to neutralize injected formulas or commands that could execute in spreadsheet applications.
Requires timely remediation of the identified flaw in CSV injection handling to prevent exploitation.

Deeper analysisAI
CVE-2023-51311 is a CSV Injection vulnerability in PHPJabbers Car Park Booking System version 3.0. The issue arises from insufficient input validation in the Languages section Labels any parameters field within System Options, where user-supplied data is used to construct CSV files. This flaw, associated with CWE-1236, has a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
An authenticated attacker with low privileges can exploit the vulnerability remotely with low complexity and no user interaction required. By injecting malicious payloads into the affected field, the attacker can embed executable formulas or commands in the resulting CSV file, potentially leading to remote code execution when the file is opened in a spreadsheet application like Microsoft Excel.
