CVE-2025-26014

9.8 CRITICAL

📋 TL;DR

A critical Remote Code Execution vulnerability in Loggrove v1.0 allows attackers to execute arbitrary code on affected systems by manipulating the path parameter. This affects all deployments of Loggrove v1.0, potentially compromising the entire system where the software runs. Attackers can gain full control over vulnerable installations.

💻 Affected Systems

Products:
  • Loggrove
Versions: v1.0
Operating Systems: All operating systems where Loggrove v1.0 runs
Default Config Vulnerable: ⚠️ Yes
Notes: All installations of Loggrove v1.0 are vulnerable regardless of configuration. No special settings are required for exploitation.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise leading to data theft, ransomware deployment, lateral movement within networks, and persistent backdoor installation.

🟠

Likely Case

Attackers gain shell access to the server, install cryptocurrency miners or malware, and exfiltrate sensitive data from the system.

🟢

If Mitigated

With proper network segmentation and strict access controls, impact could be limited to the isolated Loggrove service container or VM.

🌐 Internet-Facing: HIGH - The vulnerability is remotely exploitable without authentication, making internet-facing instances immediate targets.
🏢 Internal Only: HIGH - Even internal instances are vulnerable to insider threats or compromised internal systems.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

The vulnerability is in the path parameter which is typically user-controlled input. Exploitation requires minimal technical skill given the public details.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: No official vendor advisory found

Restart Required: Yes

Instructions:

1. Check the project repositories for updates. 2. If a patched version exists, download and install it. 3. Restart the Loggrove service. 4. Verify the fix is applied.

🔧 Temporary Workarounds

Network Isolation

linux

Restrict network access to Loggrove instances using firewall rules

iptables -A INPUT -p tcp --dport [LOGGROVE_PORT] -s [TRUSTED_NETWORK] -j ACCEPT
iptables -A INPUT -p tcp --dport [LOGGROVE_PORT] -j DROP

Web Application Firewall

all

Deploy WAF rules to block malicious path parameter patterns

🧯 If You Can't Patch

  • Immediately take Loggrove instances offline until a fix is available
  • Implement strict network segmentation and monitor all traffic to/from Loggrove instances

🔍 How to Verify

Check if Vulnerable:

Check if Loggrove version is 1.0 by examining the application or checking the installation directory for version files

Check Version:

Check application logs, configuration files, or run: find / -name '*loggrove*' -type f | xargs grep -l 'version' 2>/dev/null

Verify Fix Applied:

Verify that the path parameter no longer accepts malicious input by testing with controlled payloads

📡 Detection & Monitoring

Log Indicators:

  • Unusual path parameter values in access logs
  • System command execution patterns in application logs
  • Unexpected process spawns from Loggrove

Network Indicators:

  • Unusual outbound connections from Loggrove server
  • Traffic to known malicious IPs or domains
  • Unexpected port scans originating from Loggrove host

SIEM Query:

source="loggrove_access.log" AND (path="*;*" OR path="*|*" OR path="*`*" OR path="*$(*" OR path="*%28*%29*")
