CWE-20Published: June 2, 2011· Updated: Jun 16, 2026
6.5
CVSS v3.1
Official Description
Eucalyptus before 2.0.3 and Eucalyptus EE before 2.0.2, as used in Ubuntu Enterprise Cloud (UEC) and other products, do not properly interpret signed elements in SOAP requests, which allows man-in-the-middle attackers to execute arbitrary commands by modifying a request, related to an "XML Signature Element Wrapping" or a "SOAP signature replay" issue.
Technical Analysis
CVE-2011-0730 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
