Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:HSummary
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 User Execution (T1204); ranked at the 45th 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.

Secure SDLC practices directly require output neutralization for untrusted CSV content to block formula injection.

Security testing in development can detect formula injection but does not itself implement the mitigation.
Secure SDLC mandates input validation and output encoding that directly prevents formula injection in CSV exports.
Application security requirements include rules for safe CSV generation and handling of untrusted data.
Secure architecture principles encourage safe data export design but do not specifically address CSV formula neutralization.
Secure coding standards explicitly require neutralization of special characters when writing CSV files.
