CVE-2022-45536 is a SQL Injection vulnerability identified in AeroCMS version 0.0.1, specifically affecting the 'id' parameter in the \admin\post_comments.php script. SQL Injection (CWE-89) vulnerabilities allow an attacker to manipulate backend SQL queries by injecting malicious input, potentially leading to unauthorized access to or disclosure of sensitive database information. In this case, the vulnerability is exploitable remotely over the network (Attack Vector: Network) with low attack complexity, but requires high privileges (PR:H) and no user interaction (UI:N). The vulnerability impacts confidentiality (C:H) but does not affect integrity or availability. The vulnerability is unpatched as no patch links are provided, and there are no known exploits in the wild at the time of publication (November 22, 2022). AeroCMS is a content management system, and the affected script is part of the administrative interface, which implies that exploitation requires authenticated access to the admin panel. The vulnerability allows attackers with admin privileges to extract sensitive data from the database by exploiting improper input sanitization in the 'id' parameter, potentially exposing user data, configuration details, or other confidential information stored in the database. Given the requirement for administrative privileges, the attack surface is limited to users who have already gained some level of trusted access, but the vulnerability significantly elevates the risk of data leakage within compromised environments.

For European organizations using AeroCMS, this vulnerability poses a moderate risk primarily to the confidentiality of sensitive data stored within the CMS database. Since exploitation requires administrative privileges, the threat is most severe in scenarios where credential compromise or insider threats exist. Successful exploitation could lead to unauthorized disclosure of personal data, intellectual property, or business-critical information, potentially violating GDPR regulations and resulting in legal and financial repercussions. The exposure of sensitive data could also undermine customer trust and damage organizational reputation. Additionally, if AeroCMS is used in sectors with high data sensitivity such as healthcare, finance, or government, the impact could be more pronounced. The vulnerability does not directly affect system integrity or availability, so it is less likely to cause service disruption. However, data breaches stemming from this vulnerability could trigger incident response costs and regulatory scrutiny. European organizations with AeroCMS deployments should be particularly vigilant about access controls and monitoring of administrative accounts to mitigate the risk of exploitation.

1. Restrict administrative access: Limit access to the AeroCMS admin panel to trusted personnel and enforce strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of credential compromise. 2. Input validation and parameterized queries: Review and update the \admin\post_comments.php code to implement proper input validation and use parameterized SQL queries or prepared statements to eliminate SQL Injection risks. 3. Monitor and audit admin activities: Implement logging and real-time monitoring of administrative actions to detect suspicious behavior indicative of exploitation attempts. 4. Network segmentation: Isolate the CMS administrative interface behind VPNs or internal networks to reduce exposure to external attackers. 5. Regular security assessments: Conduct code reviews and penetration testing focused on the admin interface to identify and remediate injection flaws proactively. 6. Incident response readiness: Prepare procedures to quickly respond to potential data breaches, including notification plans compliant with GDPR. 7. Vendor engagement: Since no official patches are available, engage with AeroCMS developers or community to advocate for a security update or consider migrating to more secure CMS platforms if AeroCMS is no longer maintained.
