CVSS Release: version 2
CVE-2013-3926: Atlassian Crowd 2.6.3 allows remote attackers to execute arbitrary commands via unspecified vectors related to a "symmetric backdoor." NOTE: as of 20130704, the vendor could not reproduce the issue, stating "We've been unable to substantiate the existence of [CVE-2013-3926]. The author of the article has not contacted Atlassian and has provided no detail, making it difficult to validate the claim... If we can confirm that there is a vulnerability, a patch will be issued.
The exploitability of CVE-2013-3926 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).
The vulnerability CVE-2013-3926 is highly exploitable since it requires low complexity and no authentication.
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-2013-3926, 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-2013-3926, 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: 1.058% (probability of exploit)
EPSS Percentile: 84.32%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 15.680000000000007% of others.
