I enumerated Spring Boot Actuator endpoints, including /actuator/heapdump, which revealed plaintext credentials for oscar190. SSH login as oscar190 was successful, though the home directory was empty. Analysis of application.properties exposed Eureka credentials (EurekaSrvr:0scarPWDisTheB3st), granting access to the Eureka dashboard. By registering a malicious microservice, I retrieved miranda.wise credentials and captured the user flag. For privilege escalation, I identified a vulnerable log_analyse.sh script, performed command injection, and created a SUID bash shell in /tmp/bash. Executing this shell provided root access, allowing retrieval of the root flag and full control of the machine.
