CVSS Release: version 2
CVE-2013-0420: Unspecified vulnerability in the VirtualBox component in Oracle Virtualization 4.0, 4.1, and 4.2 allows local users to affect integrity and availability via unknown vectors related to Core. NOTE: The previous information was obtained from the January 2013 Oracle CPU. Oracle has not commented on claims from another vendor that this issue is related to an incorrect comparison in the vga_draw_text function in Devices/Graphics/DevVGA.cpp, which can cause VirtualBox to "draw more lines than necessary."
The exploitability of CVE-2013-0420 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
CVE-2013-0420 requires high complexity, reducing its exploitability but still posing a risk.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2013-0420, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2013-0420, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 0.73% (probability of exploit)
EPSS Percentile: 80.91%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 19.090000000000003% of others.
