How to check if you’re affected

 

Run these quick checks on your Oracle EBS host (adjust paths/hosts as appropriate):

 

# Look for suspicious access attempts or known malicious IPs
grep -E "200\.107\.207\.26|185\.181\.60\.11" /var/log/nginx/*access* /var/log/httpd/*access*

# Search for possible reverse shell patterns
grep -R "bash -i" /var/log /var/www /tmp

# Review recent modifications in webroot or Oracle directories
find /u01 /opt/oracle /var/www -type f -mtime -7 -ls 2>/dev/null

 

You can also use a Nuclei template to confirm exposure:

 

nuclei -u https://your-ebs-host.example.com -t CVE-2025-61882.yaml

 

Recommended actions

 

  • Apply Oracle’s emergency patch without delay.
  • Restrict HTTP exposure — ensure only necessary network access to EBS web endpoints.
  • Monitor outbound connections and file changes post-patch.
  • Review July 2025 CPU patches, as attackers have chained this exploit with earlier ones.

 

Even patched systems should be checked for prior exploitation.
