CVE-2026-22769: Dell RecoverPoint for VMs -- Hard-Coded Credentials

Background

Dell RecoverPoint for Virtual Machines (RP4VMs) is an enterprise data protection and replication appliance used to provide continuous data protection and disaster recovery for VMware vSphere environments. As a backup and replication system, RP4VMs has access to VM data across the entire protected environment and typically integrates deeply with vCenter and ESXi infrastructure.

CVE-2026-22769 is a hard-coded credentials vulnerability (CWE-798) in RP4VMs that allows unauthenticated remote attackers to use the embedded credentials to gain OS-level access to the appliance. Because these credentials are the same across all RP4VMs installations, any attacker who obtains them (through reverse engineering the appliance firmware or via public disclosure) can authenticate to any vulnerable deployment.

CISA added this to the KEV catalog on 2026-02-18. Backup and replication infrastructure is a prime ransomware target — attackers who compromise backup systems can destroy recovery capabilities, maximizing pressure on victims to pay ransoms.

Technical Mechanism

CWE-798 (Use of Hard-coded Credentials) means the appliance contains fixed username/password or SSH key pairs embedded in its firmware or configuration that are identical across all installations.

# Conceptual: attacker uses discovered hardcoded credentials
# Credentials obtained from firmware extraction or public disclosure

# SSH access using hardcoded service account
ssh [email protected]
# Password: <hardcoded_value_from_firmware>
# Root access may be achievable via sudo or direct root credentials

# Or HTTP API access:
curl -u "service_user:hardcoded_pass" https://recoverpoint.company.com/api/
# Returns full appliance access

# From here: access to protected VM data, vCenter integration credentials

Since the credentials are identical across all installations, there is no per-deployment uniqueness — obtaining the credential for one appliance provides access to all appliances running the same firmware version.

Real-World Exploitation Evidence

CISA’s KEV listing confirms active exploitation. Backup infrastructure is specifically targeted by ransomware operators as part of “double tap” attacks: first encrypt production systems, then destroy or encrypt backups to prevent recovery. RP4VMs’ deep integration with VMware infrastructure also means a compromised appliance can provide access to vCenter credentials and ESXi management APIs, enabling complete virtualization infrastructure compromise.

Impact Assessment

• Unauthenticated remote OS access to the RP4VMs appliance with root-level privileges
• Access to all data protected by the replication system (VM disk images)
• Harvesting of vCenter/ESXi integration credentials
• Destruction of backup data to amplify ransomware impact
• Pivot to VMware vSphere infrastructure via collected credentials

Affected Versions

Remediation Steps

1. Apply Dell’s security patch for CVE-2026-22769 immediately to remove hard-coded credentials.
2. Restrict RP4VMs management network access to dedicated backup administration VLANs.
3. Audit the appliance for signs of unauthorized access in system and authentication logs.
4. Rotate all vCenter and ESXi credentials configured in or accessible from RP4VMs.
5. Verify backup integrity to confirm protected data has not been tampered with.
6. Implement network monitoring for anomalous connections to backup appliance management ports.

Detection Guidance

Log Sources: RP4VMs system logs, VMware vCenter event logs, network flow data.

IOCs: SSH or API authentication to RP4VMs from unexpected IP addresses; vCenter actions originating from the RP4VMs appliance IP; unexpected deletion or modification of replication jobs.
