Q: Root Cause? (CWE/Flaw)

🛡️ **Root Cause**: Flaw in `GroovySandbox.java` (src/main/java/...). 🔍 **CWE**: Not explicitly listed in data, but technically a **Insecure Sandbox Bypass** allowing metaprogramming to escape restrictions.

Q: Who is affected? (Versions/Components)

👥 **Affected**: Jenkins users running **Script Security Plugin version 2.49 or earlier**. 📦 **Component**: Core security mechanism for Groovy scripts in Jenkins pipelines.

Q: Is there a public Exp? (PoC/Wild Exploitation)

💣 **Public Exploits**: YES. • Multiple PoCs available on GitHub (e.g., `adamyordan`, `slowmistio`). • Nuclei templates exist for automated scanning. • Orange Tsai documented the pre-auth chain.

Q: Is it fixed officially? (Patch/Mitigation)

✅ **Official Fix**: YES. • Vendor Advisory: **SECURITY-1266**. • Update Script Security Plugin to **version 2.50+**. • RedHat issued errata **RHBA-2019:0327**.

Q: Is it urgent? (Priority Suggestion)

🔥 **Urgency**: **CRITICAL**. • High impact (RCE). • Easy to exploit (especially with chaining). • Public PoCs exist. 👉 **Action**: Patch immediately or isolate the Jenkins instance.

Question 1

What is this vulnerability? (Essence + Consequences)

Accepted Answer

🚨 **Essence**: Jenkins Script Security Plugin < 2.49 has a sandbox bypass flaw.
💥 **Consequences**: Attackers can execute **arbitrary code** on the Jenkins master JVM.…

Question 2

Root Cause? (CWE/Flaw)

Accepted Answer

🛡️ **Root Cause**: Flaw in `GroovySandbox.java` (src/main/java/...).
🔍 **CWE**: Not explicitly listed in data, but technically a **Insecure Sandbox Bypass** allowing metaprogramming to escape restrictions.

Question 3

Who is affected? (Versions/Components)

Accepted Answer

👥 **Affected**: Jenkins users running **Script Security Plugin version 2.49 or earlier**.
📦 **Component**: Core security mechanism for Groovy scripts in Jenkins pipelines.

Question 4

What can hackers do? (Privileges/Data)

Accepted Answer

💰 **Attacker Capabilities**:
1. Execute **arbitrary code** on the master node.
2. Gain **Overall/Read** or **Job/Configure** permissions.
3.…

Question 5

Is exploitation threshold high? (Auth/Config)

Accepted Answer

🔓 **Threshold**:
• **Standard**: Requires **Overall/Read** + **Job/Configure** permissions.
• **Advanced**: Can be chained with **CVE-2018-1000861** for **Pre-Auth RCE** (no login needed!).…

Question 6

Is there a public Exp? (PoC/Wild Exploitation)

Accepted Answer

💣 **Public Exploits**: YES.
• Multiple PoCs available on GitHub (e.g., `adamyordan`, `slowmistio`).
• Nuclei templates exist for automated scanning.
• Orange Tsai documented the pre-auth chain.

Question 7

How to self-check? (Features/Scanning)

Accepted Answer

🔍 **Self-Check**:
1. Check Jenkins Plugin Manager for **Script Security Plugin** version.
2. Use **Nuclei** templates (`CVE-2019-1003000.yaml`).
3.…

Question 8

Is it fixed officially? (Patch/Mitigation)

Accepted Answer

✅ **Official Fix**: YES.
• Vendor Advisory: **SECURITY-1266**.
• Update Script Security Plugin to **version 2.50+**.
• RedHat issued errata **RHBA-2019:0327**.

Question 9

What if no patch? (Workaround)

Accepted Answer

🚧 **No Patch Workaround**:
1. **Disable** the Script Security Plugin if not needed (risky).
2. Restrict **Overall/Read** permissions strictly.
3.…

Question 10

Is it urgent? (Priority Suggestion)

Accepted Answer

🔥 **Urgency**: **CRITICAL**.
• High impact (RCE).
• Easy to exploit (especially with chaining).
• Public PoCs exist.
👉 **Action**: Patch immediately or isolate the Jenkins instance.
