A vulnerability has been identified in Automation License Manager V5 (All versions), Automation License Manager V6 (All versions < V6.0 SP9 Upd4), and TeleControl Server Basic V3 (All versions < V3.1.2). This vulnerability allows an unauthenticated remote attacker to rename and move files as SYSTEM user through user-chosen input without authentication. The impact is significant, as it can lead to unauthorized file manipulation.
With a CVSS score of 8.2, this vulnerability is classified as high severity, indicating a serious risk to organizations using the affected products. The potential for exploitation is high, as attackers may leverage this vulnerability to perform unauthorized actions on critical files.
Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability. The exploitability score of 3.9 further emphasizes the urgency for defenders to act quickly.
The urgency for remediation is underscored by the fact that this vulnerability affects multiple versions of the Automation License Manager, making it widely applicable in various deployment environments.
Vulnerability Details
The official description states that the affected components allow renaming of license files using user input without authentication. This could allow an unauthenticated remote attacker to manipulate files as SYSTEM user, posing significant risks to confidentiality and integrity.
The CVSS score of 8.2 indicates a high severity level, with a low attack complexity and no privileges required for exploitation. The vulnerability's integrity impact is rated high, while availability impact is low, and confidentiality impact is none.
The affected products include the Automation License Manager versions 5.0.0 to 6.0.9, covering a broad range of deployments. The vulnerability was published on January 10, 2023, and has since been marked as modified, indicating ongoing developments or updates related to its mitigation.
Technical Analysis
The root cause of this vulnerability lies in the lack of proper input validation, allowing attackers to rename files without authentication. The attack vector is network-based, meaning that an attacker does not need physical access to the system to exploit this vulnerability.
Attack complexity is low, as no special conditions or privileges are required for exploitation. User interaction is also not necessary, allowing attackers to perform actions remotely and without user consent.
The potential impacts of this vulnerability include high integrity impact, as unauthorized file renaming could compromise the integrity of the system's operations. Availability impact is low, which means the system remains operational; however, unauthorized file manipulation poses a significant risk.
Risk & Impact Analysis
Risk to organizations includes unauthorized manipulation of critical files, which could lead to operational disruptions or data integrity issues. The blast radius potential is significant, given the broad applicability of the affected products across industries.
Organizations should assess their deployment of the Automation License Manager and prioritize remediation based on the CVSS score and urgency assessment. The absence of known exploitation in the wild does not diminish the risk; proactive measures are essential.
With the CVSS score indicating a high severity, organizations are advised to address this vulnerability in their priority patch cycle to prevent unauthorized access and maintain operational integrity.
