Successful exploitation could lead to a complete account takeover, granting an attacker the same privileges as the compromised user. This could result in unauthorized access to sensitive monitoring data, manipulation of system configurations, lateral movement into other parts of the network, and potential data exfiltration. The business risks include loss of data confidentiality and integrity, disruption of IT operations, and significant reputational damage.

Remediation Plan

Immediate Action: Apply vendor security updates immediately. The vendor has released patches that introduce the necessary rate-limiting controls to the OTP verification mechanism. After patching, review authentication logs for any signs of brute-force attempts that may have occurred prior to remediation.

Proactive Monitoring: Security teams should configure monitoring and alerting for an abnormally high volume of failed authentication or OTP verification attempts originating from a single IP address or targeting a single user account. This pattern is a strong indicator of a brute-force attack. Network traffic logs should also be reviewed for rapid, repetitive requests to the application's login or OTP verification endpoints.

Compensating Controls: If immediate patching is not feasible, implement a Web Application Firewall (WAF) rule to enforce rate limiting on the OTP verification endpoint. Alternatively, configure network firewalls or security tools to temporarily block IP addresses that generate a high number of failed login attempts in a short time frame. Restricting access to the application from only trusted IP ranges can also serve as a temporary mitigating control.

Exploitation Status

Public Exploit Available: false

Analyst Notes: As of October 27, 2025, there are no known public exploits or active exploitation campaigns targeting this vulnerability.

A critical Server-Side Template Injection (SSTI) vulnerability, identified as CVE-2025-60355, has been discovered in zhangyd-c OneBlog versions prior to 2.3.9. This flaw allows an unauthenticated attacker to inject malicious code into a server-side template, leading to remote code execution. Successful exploitation could result in a complete compromise of the affected server, enabling data theft, service disruption, and further network intrusion.

Vulnerability Details

CVE-ID: CVE-2025-60355

Affected Software: zhangyd-c OneBlog

Affected Versions: All versions before 2.3.9

Vulnerability: The vulnerability is a Server-Side Template Injection (SSTI) within the FreeMarker template engine used by the OneBlog application. An attacker can submit specially crafted input to a feature that renders content using a FreeMarker template. Because the application fails to properly sanitize this user-supplied input, the template engine executes it as a directive, allowing the attacker to access the underlying server's objects and methods. This can be leveraged to execute arbitrary operating system commands with the privileges of the web server application, resulting in full Remote Code Execution (RCE).

Business Impact

This vulnerability is rated as critical severity with a CVSS score of 9.8, indicating a high risk to the organization. Successful exploitation could lead to a complete compromise of the affected server, granting an attacker full control. Potential consequences include the exfiltration of sensitive data (such as customer information, credentials, and intellectual property), deployment of ransomware, disruption of business operations, and significant reputational damage. The compromised server could also be used as a foothold to launch further attacks against the internal network, escalating the security incident.

Remediation Plan

Immediate Action: Immediately update all instances of zhangyd-c OneBlog to version 2.3.9 or later to patch the vulnerability. After patching, it is crucial to monitor for any signs of post-compromise activity and review access logs for indicators of exploitation attempts that may have occurred prior to the update.

Proactive Monitoring: Implement enhanced logging and monitoring on affected systems. Security teams should search web server access logs and application logs for suspicious patterns indicative of SSTI, such as strings containing FreeMarker syntax (e.g., ${...}, <#... >, ?new()). Monitor for unexpected child processes being spawned by the web server process (e.g., sh, bash, cmd.exe, powershell.exe) and anomalous outbound network connections from the server.

Compensating Controls: If immediate patching is not feasible, implement a Web Application Firewall (WAF) with rules specifically designed to detect and block common SSTI payloads. Additionally, ensure the application is running with the lowest possible user privileges to limit the impact of a potential compromise. Network segmentation can also help contain an attacker and prevent lateral movement from a compromised server.
