CVE-2024-41226 identifies a CSV injection vulnerability in Automation Anywhere Automation 360 version 21094. CSV injection, also known as formula injection, occurs when untrusted input is embedded into CSV files that are later opened by spreadsheet applications like Microsoft Excel. Attackers craft payloads that, when the CSV is opened, execute arbitrary code or commands on the client machine. In this case, the vulnerability allows an attacker to inject malicious formulas or scripts into CSV data generated or handled by Automation Anywhere's platform. However, Automation Anywhere disputes that this is a server-side vulnerability, stating that the malicious payload executes entirely on the client side and does not compromise the Control Room server or backend infrastructure. The CVSS 3.1 score of 8.8 reflects a high-severity rating due to the potential for remote code execution without authentication, though user interaction (opening the CSV) is required. The vulnerability is classified under CWE-1236 (Improper Neutralization of Input During Web Page Generation). No patches or exploits are currently documented, and the vendor has not acknowledged it as a valid vulnerability affecting server-side security controls. Despite this, the risk remains significant for end users who open malicious CSV files generated or exported by the affected Automation Anywhere version.

The primary impact of CVE-2024-41226 is on the confidentiality, integrity, and availability of client systems where malicious CSV files are opened. Successful exploitation can lead to arbitrary code execution on the client machine, potentially allowing attackers to steal sensitive data, install malware, or disrupt operations. Since the attack vector requires user interaction (opening a crafted CSV), social engineering or phishing campaigns could be used to deliver the payload. Organizations relying on Automation Anywhere Automation 360 for robotic process automation (RPA) may inadvertently generate or distribute malicious CSV files if input is not properly sanitized. This could lead to compromise of end-user workstations, lateral movement within networks, or data breaches. Although the Control Room server is not directly compromised, the overall security posture of organizations using this platform could be weakened. The lack of known exploits in the wild reduces immediate risk but does not eliminate the potential for future attacks.

To mitigate CVE-2024-41226, organizations should implement multiple layers of defense: 1) Sanitize all input data that may be exported to CSV files to neutralize or escape formula characters (e.g., '=', '+', '-', '@') that trigger formula execution in spreadsheet applications. 2) Educate users to be cautious when opening CSV files from untrusted or unexpected sources, especially those generated by Automation Anywhere workflows. 3) Use spreadsheet software settings or plugins that disable automatic formula execution or prompt users before running formulas. 4) Monitor and restrict the distribution of CSV files generated by Automation Anywhere to trusted recipients only. 5) Engage with Automation Anywhere for updates or patches addressing this issue and apply them promptly when available. 6) Employ endpoint protection solutions capable of detecting suspicious script execution triggered by spreadsheet applications. 7) Review and harden RPA workflows to validate and sanitize data inputs rigorously before export. These steps reduce the likelihood of successful exploitation and limit the impact on client systems.
