Server-Side Request Forgery (SSRF): Risks, Prevention & Security Best Practices

Server-Side Request Forgery (SSRF) is a critical web security vulnerability where attackers manipulate a server into making unintended requests, potentially exposing sensitive data, accessing internal resources, or executing malicious commands. Cybercriminals exploit SSRF flaws to bypass firewalls and gain unauthorized access to restricted environments. To mitigate SSRF attacks, developers should implement proper input validation, restrict outbound requests, and use allowlists for safe URLs. Strengthening server security and monitoring for suspicious activity are essential steps to protecting applications from SSRF threats.

Over 400 IPs Exploiting Multiple SSRF Vulnerabilities in Coordinated Cyber Attack

Ravi Jain
A coordinated cyberattack involving over 400 IP addresses is exploiting multiple Server-Side Request Forgery (SSRF) vulnerabilities across various platforms, including critical infrastructure and cloud services. This sophisticated campaign, detected by GreyNoise, aims to map internal networks, steal cloud credentials, and gain unauthorized access. The attacks leverage known CVEs and unlisted vulnerabilities in software like DotNetNuke, Zimbra, VMware, and GitLab. Organizations are advised to apply security patches, implement network controls, secure cloud metadata, monitor for suspicious activity, and validate user inputs to mitigate these significant risks. ...
