Akamai’s Web utility firewall (WAF) is meant to fend off potential assaults like distributed denial-of-service (DDoS), however a researcher found a option to bypass its protections through the use of advanced payloads to confuse its guidelines.
The researcher, often called Peter H., together with Usman Mansha, stated Akamai has since patched in opposition to the vulnerability, which was not assigned a CVE quantity. In the write-up, Peter H. defined how he used a susceptible model of Spring Boot to bypass WAF protections.
“We ended up in a position to bypass Akamai WAF and obtain Remote Code Execution (P1) utilizing Spring Expression Language injection on an utility operating Spring Boot,” the GitHub rationalization of the Akamai WAF RCE discover defined. “This was the 2nd RCE by way of SSTI we discovered on this program, after the first one, this system carried out a WAF which we have been in a position to bypass in a special a part of the appliance.”
