CVE-2018-25293 is a buffer overflow vulnerability found in Prime95 version 29.4b7. This specific vulnerability allows local attackers to crash the application by supplying an excessively long string in the optional proxy password field. By entering a payload of 6000 bytes, attackers can trigger a denial of service condition when the application attempts to process the connection settings.
The vulnerability has a CVSS score of 6.9, classified as medium severity, indicating that it poses a risk to availability without requiring authentication or user interaction to exploit. The attack vector is local, and the attack complexity is low, meaning that local threat actors can easily exploit this vulnerability.
Given that the application can crash when this vulnerability is exploited, organizations utilizing Prime95 should take immediate action to mitigate this risk. The urgency for defenders is high as the potential impact includes significant disruptions in service availability.
As of now, there are no known public exploits for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should remain vigilant and prepare for potential future exploits.
Vulnerability Details
The official description of this vulnerability states that Prime95 29.4b7 contains a buffer overflow vulnerability in the PrimeNet connection dialog. The issue arises when an excessively long string is supplied in the optional proxy password field. This buffer overflow allows local attackers to crash the application, leading to a denial of service.
The CVSS version 4.0 score is 6.9, indicating medium severity, with a high impact on availability. The vulnerability is classified under CWE-120, which refers to buffer errors.
Technical Analysis
The root cause of this vulnerability is a failure to properly validate the length of user input in the proxy password field of the PrimeNet connection dialog. This oversight allows for a buffer overflow to occur.
The attack vector is classified as local, meaning an attacker must have access to the system. The attack complexity is low, suggesting that no special conditions need to be met for the attack to succeed. No privileges are required, and user interaction is not necessary.
The availability impact is high, as the application will crash upon processing the malicious input. However, there is no confidentiality or integrity impact associated with this vulnerability.
Risk & Impact Analysis
The real-world risk associated with CVE-2018-25293 primarily revolves around the availability of the Prime95 application. Attackers may leverage this vulnerability to disrupt operations by causing unexpected crashes.
The blast radius for this vulnerability is confined to systems running the affected version of Prime95. Organizations that rely on this application for computational tasks should assess the potential impact of downtime and prioritize remediation efforts.
Organizations should address this vulnerability in their priority patch cycle. Given the medium severity rating, it is crucial to implement a fix promptly to maintain operational integrity.
