Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Default credentials baked into the image build process! ๐ฆ
๐ฅ **Consequences**: Full compromise. High impact on Confidentiality, Integrity, and Availability. Attackers get **H** (High) access immediately.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **CWE-798**: Use of Hard-coded Credentials.
๐ **Flaw**: The vulnerability stems from **default credentials** being enabled during the image construction phase. Itโs a classic 'lazy config' mistake.
Q3Who is affected? (Versions/Components)
๐ข **Vendor**: Kubernetes.
๐ฆ **Product**: Image Builder.
โ ๏ธ **Affected Versions**: **v0.1.37 and earlier**. If you are running older builds, you are exposed!
Q4What can hackers do? (Privileges/Data)
๐ต๏ธ **Privileges**: Full Control. CVSS indicates **C:H, I:H, A:H**.
๐พ **Data**: Sensitive data is at risk. Attackers can read, modify, and destroy resources without needing any special access.
Q5Is exploitation threshold high? (Auth/Config)
๐ **Threshold**: **LOW**.
๐ **Auth/Config**: **PR:N** (No Privileges Required). **AC:L** (Low Complexity). **UI:N** (No User Interaction). Itโs an open door! ๐ช
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ซ **Public Exp?**: **No**.
๐ **Status**: The `pocs` list is empty. While the flaw is critical, there is no known public Proof-of-Concept or wild exploitation yet.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan your **Image Builder** artifacts.
๐ ๏ธ **Features**: Look for hardcoded passwords in the build scripts or final images for versions **โค v0.1.37**. Check the GitHub issue #128006 for details.
Q8Is it fixed officially? (Patch/Mitigation)
โ **Fixed?**: **Yes**.
๐ฉน **Patch**: A fix is available via **Pull Request #1595** in `kubernetes-sigs/image-builder`. Check the mailing list announcement for the official patch details.
Q9What if no patch? (Workaround)
๐ง **No Patch?**: **Mitigation**.
๐ก๏ธ **Workaround**: If you cannot patch immediately, **rotate credentials** if possible. Isolate the affected images. Do not expose these images to untrusted networks.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: **CRITICAL**.
โณ **Priority**: **Immediate Action Required**. Even without a public exploit, the CVSS score is maxed out (9.8+ implied by H:H:H). Patch ASAP to prevent future attacks!
