CVE-2025-55575 is a critical SQL Injection vulnerability identified in SMM Panel version 3.1. This vulnerability allows remote attackers to execute crafted HTTP requests with the parameter action=service_detail to exploit the flaw. The vulnerability stems from improper sanitization of user input in the service_detail action, enabling attackers to inject malicious SQL code. Successful exploitation can lead to unauthorized access to sensitive information stored in the backend database, including user credentials, personal data, or configuration details. The CVSS score of 9.8 (Critical) reflects the high impact on confidentiality, integrity, and availability, with no authentication or user interaction required, and the vulnerability being exploitable remotely over the network. The CWE-89 classification confirms this is a classic SQL Injection issue, a well-known and dangerous web application vulnerability. Although no patches or known exploits in the wild are currently reported, the severity and ease of exploitation make this a significant threat. Organizations using SMM Panel 3.1 should consider this vulnerability a high priority for remediation once patches become available or consider immediate mitigations to prevent exploitation.

For European organizations, the impact of this vulnerability is substantial. SMM Panels are often used for social media marketing management, and compromised systems could lead to leakage of sensitive client data, including personal and financial information. Attackers could also manipulate or delete data, disrupt services, or leverage the compromised system as a foothold for further network intrusion. This could result in reputational damage, regulatory penalties under GDPR due to data breaches, and operational downtime. Given the critical nature of the vulnerability and the lack of authentication required, attackers can exploit this remotely, increasing the risk of widespread attacks. Organizations in sectors such as marketing agencies, digital service providers, and any entities relying on SMM Panel 3.1 are particularly at risk.

Immediate mitigation steps include implementing web application firewalls (WAFs) with specific rules to detect and block SQL injection attempts targeting the action=service_detail parameter. Organizations should conduct thorough input validation and sanitization on all user-supplied data, especially in the affected module. Until an official patch is released, restricting access to the SMM Panel interface by IP whitelisting or VPN-only access can reduce exposure. Regularly monitoring logs for suspicious queries or unusual database activity is critical for early detection. Additionally, organizations should prepare for patch deployment by testing updates in isolated environments and ensure backups are current to enable recovery if exploitation occurs. Engaging with the vendor for timely patch releases and security advisories is also essential.
