Summary

CVE-2023-51302 is a high-severity Improper Neutralization of Formula Elements in a CSV File (CWE-1236) vulnerability in Phpjabbers Hotel Booking System. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique LSASS Memory (T1003.001); ranked at the 48th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-15 (Information Output Filtering) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2023-51302 is a CSV injection vulnerability in PHPJabbers Hotel Booking System version 4.0. The flaw 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 without proper sanitization. This enables attackers to embed malicious payloads into exported CSV content.

An unauthenticated attacker (PR:N) can exploit the vulnerability over the network (AV:N) with low attack complexity (AC:L), though it requires user interaction (UI:R), such as an administrator opening the exported CSV file in a spreadsheet application like Excel. Successful exploitation leads to remote code execution, resulting in high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H), with a CVSS v3.1 base score of 8.8 and no change in scope (S:U). The issue maps to CWE-1236.

Advisories and details are available in references including the Packet Storm Security report at http://packetstormsecurity.com/files/176489/PHPJabbers-Hotel-Booking-System-4.0-CSV-Injection.html and the vendor product page at https://www.phpjabbers.com/hotel-booking-system/#sectionDemo. Security practitioners should review these for recommended mitigations, such as input validation updates or restricting CSV exports.
