Deeper analysis
CVE-2023-36877 is a spoofing vulnerability affecting Azure Apache Oozie, assigned CWE-79 and carrying a CVSS 3.1 base score of 4.5. The flaw permits an attacker to inject or alter content presented to users through the affected Azure-hosted Oozie component, consistent with cross-site scripting behavior that impacts integrity without affecting confidentiality or availability.
Exploitation requires an authenticated attacker with high privileges who can also induce a victim user to interact with a maliciously crafted request over the network. Successful abuse allows the attacker to spoof content or perform unauthorized actions within the Oozie interface while remaining under the privileges of the targeted user.
Microsoft’s advisory at the MSRC update guide recommends applying the patches or configuration updates listed for the affected Azure Apache Oozie deployments to remediate the issue.
The EPSS score rose materially from a low baseline to a peak of 0.0741 on 2025-01-22 before receding, indicating a period of increased exploitation interest after public disclosure.
