Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Git mishandles trailing carriage returns in config values. ๐ **Consequences**: Submodules are incorrectly checked out into symlinked hook directories.โฆ
๐ **Auth**: No authentication required. ๐ฑ๏ธ **UI**: Requires **User Interaction** (UI:R). ๐ค **Trigger**: Victim must run `git clone --recursive` on a malicious repository. ๐ **Network**: Attack vector is Network (AV:N).
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ฃ **Public Exp**: YES. Multiple PoCs are available on GitHub (e.g., `acheong08/CVE-2025-48384`). ๐งช **Proof**: Cloning specific test repos creates files like `/tmp/fishsucks` or `/tmp/sectest`, proving RCE capability.
Q7How to self-check? (Features/Scanning)
๐ **Check**: Look for `git clone --recursive` usage. ๐ **Scan**: Monitor for repositories containing malicious submodule configs with trailing carriage returns.โฆ
๐ก๏ธ **Fix**: Refer to GitHub Security Advisory **GHSA-vwqx-4fm8-6qc9**. ๐ฅ **Action**: Update Git to the patched version immediately. ๐ **Published**: July 8, 2025.
Q9What if no patch? (Workaround)
๐ซ **Workaround**: Avoid using `git clone --recursive` on untrusted repositories. ๐ซ **Alternative**: Clone manually without recursive submodule initialization.โฆ
๐ฅ **Priority**: **HIGH**. ๐จ **Urgency**: Critical RCE risk with public PoCs. โก **Action**: Patch immediately. ๐ **Risk**: High impact on system integrity and availability. Do not ignore!
