Vendor/Project: airbnb
Product: optica

Description

A remote code execution (RCE) vulnerability in Optica allows unauthenticated attackers to execute arbitrary code via specially crafted JSON payloads. Specially crafted JSON payloads may lead to RCE (remote code execution) on the attacked system running Optica. The vulnerability was patched in v. 0.10.2, where the call to the function `oj.load` was changed to `oj.safe_load`.

Technical Analysis

CVE-2022-41875 is a remote code execution (RCE) vulnerability identified in the Airbnb Optica software, specifically affecting versions prior to 0.10.2. The root cause of this vulnerability lies in the unsafe deserialization of untrusted JSON data. Optica uses the 'oj' Ruby gem for JSON parsing, and the vulnerable versions utilize the 'oj.load' function, which does not safely handle untrusted input. An attacker can exploit this by sending specially crafted JSON payloads that, when deserialized, allow arbitrary code execution on the host system without requiring authentication or user interaction. This vulnerability is classified under CWE-502, which pertains to deserialization of untrusted data leading to security issues. The vulnerability was addressed in version 0.10.2 by replacing 'oj.load' with 'oj.safe_load', a safer deserialization method that mitigates the risk of executing malicious code embedded in JSON payloads. There are no known exploits in the wild as of the published date (November 23, 2022), but the potential for exploitation remains significant due to the unauthenticated nature of the attack vector and the critical impact of remote code execution. The vulnerability affects any deployment of Optica versions earlier than 0.10.2, and given that Optica is a product developed by Airbnb, it is likely used in environments related to data visualization or analytics, which may be integrated into broader enterprise systems.

Potential Impact

The primary impact of this vulnerability is the potential for complete system compromise through remote code execution without any authentication. For European organizations using vulnerable versions of Optica, this could lead to unauthorized access, data theft, manipulation, or destruction, and could serve as a foothold for further lateral movement within corporate networks. The integrity and confidentiality of sensitive data processed or visualized by Optica could be severely compromised. Additionally, availability could be affected if attackers deploy ransomware or disrupt services. Given that the vulnerability requires no user interaction and can be triggered remotely, the attack surface is broad, increasing the risk of exploitation. For organizations in regulated sectors such as finance, healthcare, or critical infrastructure within Europe, the consequences could include regulatory penalties, reputational damage, and operational disruptions. The lack of known exploits in the wild currently reduces immediate risk, but the medium severity rating should not lead to complacency, as the vulnerability is straightforward to exploit and impactful.

Mitigation Recommendations

European organizations should immediately identify any deployments of Airbnb Optica running versions prior to 0.10.2 and prioritize upgrading to version 0.10.2 or later, where the vulnerability is patched. If immediate upgrading is not feasible, organizations should implement network-level controls to restrict access to Optica services, limiting exposure to trusted internal networks only. Employing Web Application Firewalls (WAFs) with custom rules to detect and block suspicious JSON payloads can provide temporary protection. Additionally, organizations should conduct thorough logging and monitoring of Optica-related traffic to detect anomalous deserialization attempts. Security teams should audit their software supply chain and deployment pipelines to ensure no vulnerable versions are inadvertently deployed. Finally, applying the principle of least privilege to the environment running Optica can limit the potential damage of a successful exploit by restricting the permissions available to the Optica process.
