A malicious actor with administrative privileges can upload an arbitrary file to a user-controlled location within the deployment via a system REST API.

CVSS 9.1 Critical EPSS 0.8% · p55

Should you act?

Critical, preconditions apply

Severe if exploited, but exploitation needs conditions that may not apply to you. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

  • No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
  • EPSS 0.8%, percentile 55: FIRST’s model estimates a 0.8% chance of exploitation activity in the next 30 days, higher than 55% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
  • Needs an account (high (admin)). Exposure depends on who can log in.
  • Only applies if your dependency tree includes org.wso2.carbon.apimgt:org.wso2.carbon.apimgt.rest.api.admin.v1 (Maven) < 9.32.167, fixed in 9.32.167. Check your lockfile, including transitive dependencies.

What it is

A malicious actor with administrative privileges can upload an arbitrary file to a user-controlled location within the deployment via a system REST API. Successful uploads may lead to remote code execution. By leveraging the vulnerability, a malicious actor may perform Remote Code Execution by uploading a specially crafted payload.
