Vulnerability details

Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 1.0.735 and Application prior to 20.0.1330 (macOS/Linux client deployments) contain a vulnerability in the local logging mechanism. Authentication session tokens, including PHPSESSID, XSRF-TOKEN, and laravel_session, are stored in cleartext within…

world-readable log files. Any local user with access to the machine can extract these session tokens and use them to authenticate remotely to the SaaS environment, bypassing normal login credentials, potentially leading to unauthorized system access and exposure of sensitive information. This vulnerability has been identified by the vendor as: V-2022-008 — Secrets Leaked in Logs.

Related Threats

MITRE ATT&CK Enterprise TechniquesAI

T1539 Steal Web Session Cookie Credential Access
An adversary may steal web application or service session cookies and use them to gain access to web applications or Internet services as an authenticated user without needing credentials.
T1552.001 Credentials In Files Credential Access
Adversaries may search local file systems and remote file shares for files containing insecurely stored credentials.
Why these techniques?

The vulnerability stores authentication session tokens (PHPSESSID, XSRF-TOKEN, laravel_session) in cleartext within world-readable log files, enabling adversaries to steal web session cookies (T1539) and access unsecured credentials in files (T1552.001) for remote SaaS authentication.

addresses: CWE-532

The process of identifying and eradicating spilled information applies directly to sensitive data inserted into log files.

addresses: CWE-532

Specific processing rules for sensitive PII categories commonly include restrictions on logging, making insertion of such data into log files less likely.

addresses: CWE-532

PIAs detect planned or existing logging of PII and require removal or protection, preventing insertion of sensitive information into logs.

addresses: CWE-532

Limits insertion of sensitive operational details into logs by treating such data as key information requiring protection.
