Q1What is this vulnerability? (Essence + Consequences)
π¨ **iTerm2 Info Leak**: A security flaw in the popular Mac terminal emulator. Attackers can read sensitive data from terminal commands by accessing the file `/tmp/framer.txt`.β¦
π‘οΈ **CWE-532**: The root cause is **Information Exposure Through Debug Information**. The application improperly exposes internal state or sensitive command history via a temporary file in the `/tmp` directory.
Q3Who is affected? (Versions/Components)
π¦ **Affected**: All versions of **iTerm2** for **Mac OS X** prior to the fix. Specifically, versions before **3.5.11** are vulnerable. It is a personal project by George Nachman.
Q4What can hackers do? (Privileges/Data)
π΅οΈ **Attacker Capabilities**: Remote attackers can **read sensitive information** directly from terminal commands.β¦
β‘ **Low Threshold**: Exploitation is **Easy**. CVSS indicates **Low Complexity** and **No Privileges** required. No user interaction is needed. The attacker just needs access to the `/tmp` directory.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π’ **Public PoC**: No specific code-based PoC provided in the data. However, the vulnerability is well-documented in the **iTerm2 Wiki** and discussed on **Hacker News**.β¦
π **Self-Check**: Check if you are running **iTerm2 < 3.5.11**. Monitor for the existence of `/tmp/framer.txt`. If present, it may contain leaked terminal session data. Use `ls -l /tmp/framer.txt` to verify presence.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed**: Yes. The vulnerability was addressed in **iTerm2 version 3.5.11**. Users should update immediately. See the official **Changelog** for details.
Q9What if no patch? (Workaround)
π οΈ **Workaround**: If you cannot update, **restrict access** to `/tmp`. Ensure no other users on the system can read files in `/tmp`. However, this is **not a full fix**; updating is strongly recommended.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency: HIGH**. CVSS Score implies **High Confidentiality Impact** and **Low Attack Complexity**. Since it affects a widely used tool and requires no auth, patch **immediately** to prevent data leakage.
