Summary
CVE-2023-53913 is a high-severity Improper Neutralization of Formula Elements in a CSV File (CWE-1236) vulnerability in Rukovoditel Rukovoditel. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 34.3th 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 are NIST 800-53 SI-10 (Information Input Validation) and SI-15 (Information Output Filtering).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Filters firstname field content during CSV export to neutralize formula injection payloads like =calc|a!z| before transmission to spreadsheet applications.
Validates and sanitizes inputs to the firstname field to prevent storage of malicious formula elements by authenticated users.
Remediates the specific flaw in Rukovoditel 3.3.1 by patching the lack of sanitization in user input handling for CSV exports.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The CSV injection vulnerability in the web application (public-facing, AV:N/PR:L) enables low-privileged authenticated users to exploit it for privilege escalation (T1068, T1190) by injecting malicious formulas into exported CSV files, facilitating arbitrary code execution via user opening of the malicious file (T1204.002).
NVD Description
Rukovoditel 3.3.1 contains a CSV injection vulnerability that allows authenticated users to inject malicious formulas into the firstname field. Attackers can craft payloads like =calc|a!z| to trigger code execution when an admin exports customer data as a CSV file.
Deeper analysisAI
CVE-2023-53913 is a CSV injection vulnerability in Rukovoditel version 3.3.1. The flaw resides in the firstname field, where authenticated users can inject malicious formulas, such as =calc|a!z|, without proper sanitization. It is classified under CWE-1236 and carries 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), reflecting high severity due to its network reach, low complexity, and potential for significant impact.
An authenticated user with low privileges can exploit this by injecting a crafted payload into their firstname field during account creation or modification. The attack activates when an administrator exports customer data to a CSV file; upon opening the file in a spreadsheet application like Excel or LibreOffice, the injected formula executes arbitrary code on the administrator's local machine, potentially leading to full compromise.
