CVE-2022-22110
📋 TL;DR
Daybyday CRM versions 1.1 through 2.2.0 allow users to set extremely weak passwords (including single-character passwords) when updating their credentials. This vulnerability enables attackers to brute-force user accounts with minimal computational effort. Organizations using affected versions of Daybyday CRM are at risk.
💻 Affected Systems
- Daybyday CRM
📦 What is this software?
Daybyday Crm by Daybydaycrm
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain unauthorized access to all user accounts through trivial brute-force attacks, leading to complete system compromise, data theft, and privilege escalation.
Likely Case
Attackers compromise individual user accounts through automated password guessing, potentially accessing sensitive CRM data and performing unauthorized actions.
If Mitigated
With strong password policies and monitoring, impact is limited to failed login attempts that trigger alerts.
🎯 Exploit Status
Exploitation requires user credentials to access password update functionality, but weak passwords can then be brute-forced trivially.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.2.1 and later
Vendor Advisory: https://github.com/Bottelet/DaybydayCRM/commit/a0392f4a4a14e1e3fedaf6817aefce69b6bd661b
Restart Required: No
Instructions:
1. Update Daybyday CRM to version 2.2.1 or later. 2. Apply the patch from the GitHub commit. 3. No restart required.
🔧 Temporary Workarounds
Enforce Strong Password Policy
allImplement server-side password validation requiring minimum length (8+ characters), complexity, and prevent common weak passwords.
Modify password validation logic in user update functionality
🧯 If You Can't Patch
- Enforce strong password policies through external authentication systems (e.g., LDAP/AD integration).
- Implement account lockout policies after failed login attempts and monitor authentication logs.
🔍 How to Verify
Check if Vulnerable:
Attempt to update a user password to a single character via the user update functionality. If successful, the system is vulnerable.
Check Version:
Check Daybyday CRM version in admin panel or configuration files.
Verify Fix Applied:
After patching, attempt to set a weak password (single character). The system should reject it with appropriate error messages.
📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts from single IP
- Successful login after many failures
- Password update requests with weak passwords
Network Indicators:
- Unusual authentication traffic patterns
- Brute-force attack tools traffic
SIEM Query:
source="daybyday_logs" AND (event="failed_login" OR event="password_change") | stats count by src_ip, user
