Vulnerability Details
The official description of this vulnerability states that the Symantec Diagnostic Tool (SymDiag), prior to version 3.0.79, may be susceptible to a privilege escalation vulnerability. It is classified under CWE-269, which pertains to privilege escalation issues.
The CVSS version 3.1 vector string for this vulnerability is CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. This indicates a local attack vector with low complexity, where the attacker requires low privileges and no user interaction is necessary. The impacts are significant, with high effects on confidentiality, integrity, and availability.
Published on February 19, 2025, this vulnerability is categorized as high severity due to its potential impact on systems using the affected version of the Symantec Diagnostic Tool.
Technical Analysis
The root cause of CVE-2025-0893 is related to improper privilege management within the Symantec Diagnostic Tool. This vulnerability can be exploited if an attacker gains access to a local system and leverages the vulnerabilities in the tool to escalate their privileges.
The attack vector is local, meaning an attacker must have access to the machine running the Symantec Diagnostic Tool. The attack complexity is low, indicating that exploiting this vulnerability does not require advanced skills or knowledge. The privileges required to exploit this vulnerability are also low, making it easier for attackers to gain unauthorized access.
User interaction is not required for exploitation, further enhancing the risk. If exploited, the vulnerability can lead to significant impacts on confidentiality, integrity, and availability of the affected systems.
Risk & Impact Analysis
The real-world risk associated with CVE-2025-0893 is substantial. Given that it allows privilege escalation, an attacker could potentially gain control over critical functionalities of the system, leading to unauthorized access to sensitive data or resources. The blast radius could be considerable, impacting not only the individual systems running the tool but potentially the broader organizational infrastructure.
Organizations that deploy the Symantec Diagnostic Tool must understand the implications of this vulnerability. The urgency for addressing this issue is high, as exploitation could lead to severe breaches of security and data integrity. Organizations should prioritize remediation efforts based on the CVSS score of 7.8, which signifies a high level of risk.
As the situation evolves, it is crucial for organizations to stay informed about any developments related to this vulnerability and adjust their security protocols accordingly.
