Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Apache ServiceComb Service-Center versions prior to 2.1.0 contain a Server-Side Request Forgery vulnerability tracked as CVE-2023-44313. The flaw resides in the handling of incoming requests and is classified under CWE-918, carrying a CVSS 3.1 score of 7.6.

An unauthenticated remote attacker can submit specially crafted requests that cause the service-center to fetch arbitrary resources, resulting in disclosure of sensitive server information along with limited impact to integrity and availability.

Apache advisories direct users to upgrade to version 2.2.0, which resolves the issue, and reference lists on lists.apache.org and openwall.com provide the corresponding security announcements. The associated EPSS score has remained at 0.6909 without a documented rise from a lower baseline.

Mitigating Controls (NIST 800-53 r5) AI

AC-4 Information Flow Enforcement good match

Information flow enforcement can restrict which destinations the server is allowed to contact on behalf of users.

SI-10 Information Input Validation good match

Input validation directly stops untrusted URLs from being accepted and fetched without destination checks.

SC-7 Boundary Protection partial match

Boundary protection limits the network reach of server-initiated requests even if SSRF occurs.
