CVE-2025-1387

Comprehensive Technical Analysis of CVE-2025-1387

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-1387 CISA Vulnerability Name: CVE-2025-1387 Description: Orca HCM from LEARNING DIGITAL has an Improper Authentication vulnerability, allowing unauthenticated remote attackers to log in to the system as any user. CVSS Score: 9.8

The CVSS score of 9.8 indicates a critical vulnerability. This high score is due to the potential for unauthenticated remote attackers to gain full access to the system, leading to significant impacts on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: Attackers can exploit the vulnerability to bypass authentication mechanisms and log in as any user without valid credentials.
• Remote Exploitation: The vulnerability can be exploited remotely, meaning attackers do not need physical access to the system.

Exploitation Methods:

• Credential Stuffing: Attackers may use known usernames and bypass the authentication process to gain access.
• Automated Scripts: Malicious actors could use automated scripts to repeatedly attempt to log in as different users until successful.
• Phishing: Attackers could use phishing techniques to trick users into revealing their usernames, which can then be used to exploit the vulnerability.

3. Affected Systems and Software Versions

Affected Systems:

• Orca HCM from LEARNING DIGITAL

Software Versions:

• Specific versions affected are not mentioned in the provided information. It is crucial to identify the exact versions impacted by this vulnerability to ensure targeted mitigation.

4. Recommended Mitigation Strategies
