Overview
CVE-2025-12784 describes a potential information disclosure vulnerability affecting certain HP LaserJet Pro printers. This vulnerability could allow an attacker to gain access to sensitive information, potentially including credentials, by manipulating scan/send destination addresses and/or modifying the LDAP server configuration.
Technical Details
The vulnerability stems from insufficient validation and access controls related to the scan/send functionality and LDAP server configuration within the affected HP LaserJet Pro printers. Specifically, an attacker could potentially:
- Alter Scan/Send Destination Address: Redirect scanned documents to an unauthorized recipient.
- Modify LDAP Server Settings: Compromise the LDAP server settings potentially leading to unauthorized access or information disclosure from the configured LDAP server.
Successful exploitation could lead to the disclosure of sensitive information contained within scanned documents or credentials used for network authentication.
CVSS Analysis
Currently, the CVSS score and severity for CVE-2025-12784 are listed as N/A. This may indicate that the vulnerability is still under investigation or that the impact is considered to be context-dependent. It is crucial to monitor HP’s security advisories for updated risk assessments.
Possible Impact
The potential impact of CVE-2025-12784 can be significant. Exploitation of this vulnerability could lead to:
- Data Breach: Exposure of sensitive information contained in scanned documents, such as financial records, personal identifiable information (PII), or proprietary business data.
- Credential Compromise: Unauthorized access to network resources through compromised LDAP server credentials.
- Lateral Movement: An attacker could leverage compromised credentials to move laterally within the network and access other systems.
- Reputational Damage: Loss of customer trust and damage to the organization’s reputation.
Mitigation and Patch Steps
HP has released a security bulletin with specific instructions and potentially firmware updates to address this vulnerability. Follow these steps to mitigate the risk:
- Apply the Latest Firmware Updates: Immediately apply the firmware updates provided by HP for your specific LaserJet Pro printer model. This is the primary method to address the underlying vulnerability.
- Review Scan/Send Settings: Carefully review the scan/send destination addresses configured on your printers to ensure they are legitimate and authorized.
- Strengthen LDAP Security: If your printers are configured to use an LDAP server, ensure that strong authentication methods are in place and that access controls are properly configured. Consider using TLS/SSL to encrypt communication between the printer and the LDAP server.
- Network Segmentation: Isolate printers on a separate network segment to limit the potential impact of a successful attack.
- Monitor Printer Activity: Implement logging and monitoring to detect suspicious activity related to printer configurations and network traffic.
