CVE-2022-1262

7.8 HIGH

📋 TL;DR

CVE-2022-1262 is a command injection vulnerability in the protest binary that allows authenticated attackers with CLI access to execute arbitrary commands with root privileges. This affects systems running vulnerable versions of the protest software with the remote command line interface enabled. Attackers can gain complete system control through this vulnerability.

💻 Affected Systems

Products:
  • protest binary/software
Versions: Specific vulnerable versions not specified in provided references; check vendor advisory for exact range.
Operating Systems: Linux/Unix systems where protest binary runs
Default Config Vulnerable: ⚠️ Yes
Notes: Requires protest binary with remote command line interface enabled and accessible to attackers.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full system compromise with root-level command execution, allowing data theft, system destruction, or persistent backdoor installation.

🟠

Likely Case

Unauthorized command execution leading to data exfiltration, lateral movement within the network, or deployment of malware.

🟢

If Mitigated

Limited impact with proper network segmentation and access controls preventing exploitation attempts.

🌐 Internet-Facing: HIGH if protest binary with remote CLI is exposed to internet, as authenticated attackers can gain root access.
🏢 Internal Only: MEDIUM to HIGH depending on internal network segmentation and access controls for the protest CLI interface.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires access to the remote CLI interface but is straightforward once authenticated.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check vendor advisory for specific patched version

Vendor Advisory: https://www.tenable.com/security/research/tra-2022-09

Restart Required: Yes

Instructions:

1. Check current protest version. 2. Apply vendor-provided patch or update to fixed version. 3. Restart protest service. 4. Verify patch application.

🔧 Temporary Workarounds

Disable Remote CLI Access

linux

Disable the remote command line interface if not required for operations

Check protest configuration for CLI settings and disable remote access

Network Access Controls

linux

Restrict network access to protest CLI interface using firewall rules

iptables -A INPUT -p tcp --dport [PROTEST_CLI_PORT] -j DROP
ufw deny [PROTEST_CLI_PORT]

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate protest systems from critical assets
  • Enforce least privilege access controls and monitor all CLI access attempts

🔍 How to Verify

Check if Vulnerable:

Check protest version against vendor advisory and verify remote CLI is enabled

Check Version:

protest --version or check installed package version

Verify Fix Applied:

Verify protest version is updated to patched version and test command injection attempts

📡 Detection & Monitoring

Log Indicators:

  • Unusual command execution via protest CLI
  • Multiple failed authentication attempts to protest interface
  • Suspicious process spawning from protest binary

Network Indicators:

  • Unexpected connections to protest CLI port
  • Command injection patterns in network traffic to protest service

SIEM Query:

source="protest.log" AND (command="*;*" OR command="*|*" OR command="*`*" OR command="*$(*)")
