CVE-2022-40955 is a high-severity vulnerability affecting Apache InLong versions prior to 1.3.0. Apache InLong is an open-source data integration framework developed by the Apache Software Foundation, designed to collect, aggregate, and transmit large volumes of data. The vulnerability arises from unsafe deserialization of untrusted data, classified under CWE-502. Specifically, an attacker who has sufficient privileges to specify MySQL JDBC connection URL parameters and write arbitrary data into the MySQL database used by Apache InLong can exploit this flaw. The unsafe deserialization occurs when Apache InLong reads and processes this maliciously crafted data from the database, leading to the potential execution of arbitrary code on the server hosting Apache InLong. This can result in full remote code execution (RCE) without requiring user interaction, and with low attack complexity due to network accessibility and low authentication requirements (privileged user access to database connection parameters and write permissions). The vulnerability impacts confidentiality, integrity, and availability of the affected systems, as attackers can execute arbitrary commands, potentially leading to data breaches, service disruption, or further lateral movement within the network. The Apache Software Foundation has addressed this issue in Apache InLong version 1.3.0 and later, and users are strongly advised to upgrade to these versions to mitigate the risk. No known exploits in the wild have been reported to date, but the high CVSS score of 8.8 reflects the critical nature of this vulnerability if exploited.

For European organizations, the impact of CVE-2022-40955 can be significant, especially for those relying on Apache InLong for data integration and processing in critical infrastructure, financial services, telecommunications, and large enterprises managing big data workflows. Exploitation could lead to unauthorized remote code execution on servers, resulting in data exfiltration, manipulation of sensitive information, disruption of data pipelines, and potential compliance violations under GDPR due to data breaches. The ability to execute arbitrary code remotely can also facilitate further attacks within the network, including ransomware deployment or espionage. Given the interconnected nature of European IT environments and the increasing reliance on data-driven operations, this vulnerability poses a substantial risk to operational continuity and data security. Organizations with privileged users who can configure database connection parameters and write to the MySQL backend are particularly at risk, emphasizing the need for strict access controls and monitoring.

To mitigate CVE-2022-40955, European organizations should: 1) Immediately upgrade Apache InLong to version 1.3.0 or later, where the vulnerability is patched. 2) Restrict and audit privileges related to database connection configurations, ensuring only trusted administrators have the ability to specify JDBC URL parameters and write data to the MySQL database. 3) Implement strict input validation and sanitization on data written to the database to prevent injection of malicious serialized objects. 4) Employ network segmentation and firewall rules to limit access to Apache InLong servers and associated databases, reducing the attack surface. 5) Monitor logs and database transactions for unusual activities indicative of exploitation attempts, such as unexpected serialized data or anomalous connection parameter changes. 6) Conduct regular security assessments and penetration testing focused on deserialization vulnerabilities and privilege escalation paths. 7) Consider deploying runtime application self-protection (RASP) or application-layer firewalls capable of detecting and blocking deserialization attacks. These targeted measures go beyond generic patching and help reduce the risk of exploitation in complex enterprise environments.
