Oxeye, the supplier of award-winning cloud-native utility safety, right this moment introduced that its safety researchers have uncovered a number of new excessive severity variants of the IDOR (Insecure Director Object Reference) vulnerabilities in CNCF-graduated mission Harbor, the favored open-source artifact registry by VMware.
Harbor is an open-source cloud native registry mission that shops, indicators and scans content material. It could actually combine with varied Docker registries to supply safety features similar to consumer administration, entry management and exercise auditing.
Categorized as an entry management vulnerability, IDOR happens when an utility makes use of user-supplied enter to entry objects straight. IDOR is a excessive severity menace and is taken into account to be probably the most critical internet utility safety danger on probably the most present OWASP prime 10 record.
Entry management methods are designed to implement insurance policies that stop customers from appearing outdoors of meant permissions.
Entry management failures usually result in unauthorized info disclosure, modification, knowledge deletion, or the efficiency of enterprise features outdoors of a consumer’s limits.
On this analysis, IDOR was found in VMware’s Harbor, which permits customers to higher handle their utility artifacts. Function-based entry management (RBAC) in place is often a finest follow towards IDOR vulnerabilities, however this analysis examined that principle with shocking outcomes.
The IDOR vulnerability in Harbor results in the disclosure of webhook insurance policies with out authorization. Harbor permits customers to configure webhook insurance policies to obtain notifications about sure occasions within the repository, e.g., when a brand new artifact is pushed or when an present one is deleted.
As soon as a webhook coverage is added, a Harbor consumer could view particulars of the created webhook insurance policies.
On this instance, the vulnerability occurred as a result of Harbor solely tried to validate that the requesting consumer had entry to the mission ID specified within the request.
But it surely did not validate that the requested webhook ID belonged to the desired mission ID.
One other IDOR variant results in the disclosure of job execution logs. P2P (peer-to-peer) preheating permits Harbor customers to combine with P2P engines similar to Dragonfly or Kraken to distribute Docker pictures at scale.
By combining this IDOR vulnerability with the “ParseThru” vulnerability recognized beforehand by the Oxeye analysis staff, an attacker could have the power to learn Docker picture layers to which they lack entry credentials.
The next IDOR CVE numbers hyperlink again to GitHub and are related to the vulnerabilities talked about above.
“Whereas role-based entry management (RBAC) is vital for sustaining a powerful safety place, it isn’t the end-all for absolute system protection towards IDOR vulnerabilities,” stated Ron Vider, CTO and Co-founder, Oxeye.
“As revealed by Oxeye safety researchers Gal Goldshtein and Daniel Abeles, implementing extra sturdy practices that embrace setting strict roles for API endpoints, simulating menace actors to check these roles in an try to interrupt permission fashions, and avoiding property duplication to take care of a single supply of reality can guarantee resiliency.”
All IDOR variants talked about on this announcement have been communicated to the VMware Safety Response and Harbor Engineering groups, who promptly collaborated in the direction of a fast and efficient decision. All have been addressed (mounted) within the newest model of Harbor.

“The standard of the open supply software program and industrial distributions we and our companions distribute is important to us and to the organizations that use it. We’re grateful to Oxeye and its researchers for his or her diligence find vulnerabilities and their wonderful collaboration in serving to us deal with them.” – Roger Klorese, Product Line Supervisor, Venture Harbor, VMware
