CVE-2013-1840 — Openstack glance: swift: s3: openstack glance: information disclosure of backend credentials via cached image request

A flaw was found in OpenStack Glance. Remote authenticated users can exploit this vulnerability by requesting a cached image when the single-tenant Swift or S3 store is in use. This action causes the system to report the location field, which can lead to the disclosure of the operator's backend credentials.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 1.4% (30-day exploitation probability)+11
  • Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

  • Pip Glance: fixed in version 11.0.0a0 — github.com (GitHub Security Advisories)

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (OpenStack Glance, Red Hat OpenStack Folsom for RHEL 6, Pip Glance).
  2. Apply the fixed version or the patch documented under Remediation.
  3. Search available logs for exploit probes matching the vulnerability class (info disclosure), errors and authentication anomalies.
