CVE-2024-0890 is a critical SQL Injection vulnerability identified in hongmaple octopus version 1.0, specifically within an unknown function located in the /system/dept/edit file. The vulnerability arises from improper sanitization or validation of the 'ancestors' argument, which allows an attacker to inject malicious SQL code remotely. This injection can manipulate backend database queries, potentially leading to unauthorized data access, data modification, or disruption of service. The vulnerability is remotely exploitable without requiring user interaction, but it does require some level of privileges (PR:L) according to the CVSS vector, indicating that an attacker must have limited privileges to exploit it. The product uses continuous delivery with rolling releases, complicating the identification of affected versions and patches. No official patches or updated releases have been disclosed yet. Although the CVSS score is 6.3 (medium severity), the classification as critical in the description suggests that the impact could be significant depending on deployment context. The vulnerability affects confidentiality, integrity, and availability of the system, as SQL Injection can lead to data leakage, unauthorized data manipulation, or denial of service. No known exploits are currently reported in the wild, but public disclosure increases the risk of exploitation attempts.

For European organizations using hongmaple octopus 1.0, this vulnerability poses a significant risk. SQL Injection vulnerabilities can lead to unauthorized access to sensitive data, including personal data protected under GDPR, potentially resulting in data breaches and regulatory penalties. The ability to remotely exploit this vulnerability without user interaction increases the attack surface, especially for internet-facing deployments. Compromise could lead to data integrity issues, affecting business operations and trustworthiness of data. Availability may also be impacted if attackers leverage the vulnerability to disrupt services. Given the continuous delivery model and lack of clear patching information, organizations may struggle to quickly remediate, prolonging exposure. This is particularly critical for sectors with high data sensitivity such as finance, healthcare, and government services within Europe. Additionally, the requirement for limited privileges to exploit the vulnerability suggests that insider threats or compromised accounts could be leveraged to escalate attacks.

European organizations should immediately audit their deployments of hongmaple octopus to determine if version 1.0 or affected builds are in use. Since no official patches are available, organizations should implement compensating controls: 1) Restrict access to the /system/dept/edit endpoint to trusted internal networks or authenticated users with strict privilege controls. 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'ancestors' parameter. 3) Conduct thorough input validation and sanitization at the application layer, if source code access is available, to neutralize injection attempts. 4) Monitor logs for suspicious database query patterns or anomalous access to the vulnerable endpoint. 5) Limit database user privileges associated with the application to the minimum necessary to reduce impact of potential injection. 6) Engage with the vendor hongmaple for timely updates or patches and consider temporary mitigation by disabling or restricting the vulnerable functionality if feasible. 7) Prepare incident response plans for potential exploitation scenarios, including data breach notification procedures compliant with GDPR.
