In the ever-evolving world of cybersecurity, a new vulnerability has surfaced that could put enterprise security at risk. Researchers have disclosed security flaws in Xerox VersaLink C7025 Multifunction Printers (MFPs) that can be exploited by attackers to capture Windows Active Directory credentials through pass-back attacks via LDAP, SMB, and FTP services. These flaws highlight the growing concerns over networked devices and their potential role in cyber threats.
Understanding the Xerox Printer Vulnerabilities
According to security researcher Deral Heiland from Rapid7, the pass-back attack technique allows malicious actors to alter the MFP’s configuration, tricking it into sending authentication credentials to an attacker-controlled system. This could lead to unauthorized access to Windows Active Directory, enabling cybercriminals to move laterally across an organization’s network.
CVE-2024-12510 and CVE-2024-12511: The Security Risks
Two specific Common Vulnerabilities and Exposures (CVEs) have been identified in firmware versions 57.69.91 and earlier:
- CVE-2024-12510 (CVSS Score: 6.7) – LDAP Pass-Back Attack:
- Allows an attacker to intercept authentication credentials by redirecting them to a rogue server.
- Requires access to the LDAP configuration page with LDAP authentication enabled.
- CVE-2024-12511 (CVSS Score: 7.6) – Pass-Back Attack via User Address Book:
- Exploits a misconfiguration in the address book, redirecting authentication data to an attacker-controlled SMB/FTP server.
- Requires either physical access to the printer console or remote control via the web interface.
These vulnerabilities present serious security concerns as attackers can leverage them to infiltrate Windows-based systems, file shares, and potentially gain access to sensitive data.
How Attackers Can Exploit These Vulnerabilities
To successfully exploit these security flaws, a malicious actor would need:
- Access to the printer’s LDAP configuration page (for CVE-2024-12510).
- The ability to modify the SMB or FTP server address in the user’s address book (for CVE-2024-12511).
- Physical access to the printer console or admin credentials to access the remote control console.
Once these conditions are met, the attacker can capture authentication credentials, allowing them to move laterally across an organization’s network, access sensitive files, and potentially compromise additional Windows servers.
Mitigation and Security Recommendations
1. Apply the Latest Xerox Firmware Update
Xerox has released a patch (Service Pack 57.75.53) for VersaLink C7020, 7025, and 7030 printers, addressing these vulnerabilities. Organizations should immediately update their devices to prevent exploitation.
2. Strengthen Authentication Security
- Use complex passwords for the printer’s admin account.
- Disable remote access to the printer console for unauthorized users.
- Avoid using privileged Windows accounts for authentication.
3. Restrict Access to Printer Configuration
- Limit access to LDAP configuration settings to prevent unauthorized modifications.
- Restrict physical and remote access to the printer’s address book settings.
4. Monitor Printer Traffic
- Log and review network activity to detect any unauthorized LDAP, SMB, or FTP requests.
- Use endpoint detection tools to identify suspicious credential exfiltration attempts.
Growing Threats in Enterprise Cybersecurity
The Xerox printer vulnerabilities aren’t the only cybersecurity risks affecting enterprises. Researchers have recently uncovered a critical SQL injection vulnerability (CVE-2024-56735) in HealthStream MSOW, a widely used healthcare software. Exploitation of this flaw could allow attackers to access sensitive patient data from healthcare organizations.
These incidents highlight the importance of proactive security measures, as attackers increasingly target enterprise IT infrastructure, printers, and networked devices.
