CVE-2023-43323 Scanner

mooSocial is a popular social networking software used by communities, social groups, and niche social networks to create their own custom social platform. It allows users to connect, share content, and engage in community-driven activities. Businesses and organizations often utilize mooSocial to foster interaction and provide a unified platform for their communities. Its user-friendly interface and customizable features make it a practical choice for both small and large social networking needs. Deployed on various scales, from local community groups to broader social projects, mooSocial offers extensive functionality. However, this flexibility can expose it to security vulnerabilities if not maintained and secured properly.

The vulnerability in question involves an externally controlled interaction with services, which can be exploited in the post function of mooSocial. This security flaw arises when certain parameters can be manipulated to make unauthorized connections to external services. Such vulnerabilities can compromise the integrity and confidentiality of the connected resources. Attackers can potentially execute unauthorized actions or gather sensitive data by influencing the external interactions. The vulnerability essentially exposes mooSocial to external service manipulation, posing a threat to data security and user trust. Addressing such vulnerabilities is crucial to maintaining a secure social networking environment.

Technical details indicate that the vulnerability stems from multiple parameters in the post function that can be exploited for unintended interactions. Parameters like `data[userShareVideo]` are susceptible, allowing URLs to be manipulated to reach an external resource. The exposure happens because these parameters are not properly sanitized before being processed. This oversight allows attackers to inject arbitrary external service calls, which could facilitate data exfiltration or service disruption. The vulnerable endpoint primarily involves the `POST /activities/ajax_share` function, making a secure patch essential. Enhancing parameter validation and restricting unauthorized external requests are necessary measures to mitigate this vulnerability.

The potential effects of exploiting this vulnerability include unauthorized access to sensitive information, potential data breaches, and unapproved interactions with external services. This could lead to data being leaked to unauthorized third parties, compromising user privacy and organizational data integrity. Additionally, attackers might use this flaw to introduce malicious content or execute harmful operations within the network. The social platform could experience disrupted services and loss of trust among users. Therefore, a successful exploitation could result in significant operational and reputational impacts on the affected organization.
