CVSS Release: version 2
CVE-2003-0813: A multi-threaded race condition in the Windows RPC DCOM functionality with the MS03-039 patch installed allows remote attackers to cause a denial of service (crash or reboot) by causing two threads to process the same RPC request, which causes one thread to use memory after it has been freed, a different vulnerability than CVE-2003-0352 (Blaster/Nachi), CVE-2003-0715, and CVE-2003-0528, and as demonstrated by certain exploits against those vulnerabilities.
The exploitability of CVE-2003-0813 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-2003-0813 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-2003-0813, 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-2003-0813, 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: 56.408% (probability of exploit)
EPSS Percentile: 97.9%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 2.0999999999999943% of others.
