CVE-2025-53763

Comprehensive Technical Analysis of CVE-2025-53763

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-53763 Description: Improper access control in Azure Databricks allows an unauthorized attacker to elevate privileges over a network. CVSS Score: 9.8

The CVSS score of 9.8 indicates a critical vulnerability. This high score is likely due to the potential for unauthorized privilege escalation, which can lead to significant security breaches. The vulnerability involves improper access control, suggesting that the existing security mechanisms in Azure Databricks are insufficient to prevent unauthorized access and privilege escalation.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Given the description, attackers could exploit this vulnerability over the network, indicating potential remote exploitation.
• Privilege Escalation: Once an attacker gains initial access, they can escalate their privileges to gain higher-level access within the Azure Databricks environment.

Exploitation Methods:

• Credential Theft: Attackers might exploit weak access controls to steal credentials or session tokens.
• Lateral Movement: With elevated privileges, attackers can move laterally within the network, accessing other systems and data.
• Data Exfiltration: Elevated privileges can allow attackers to exfiltrate sensitive data from the Azure Databricks environment.

3. Affected Systems and Software Versions

Affected Systems:

• Azure Databricks environments.
• Potentially other integrated systems that rely on Azure Databricks for data processing and analytics.

Software Versions:

• Specific versions affected are not mentioned in the provided information. However, it is crucial to identify and patch all versions of Azure Databricks that are vulnerable to this issue.
