CVE-2018-0461: A vulnerability in the Cisco IP Phone 8800 Series Software could allow an unauthenticated, remote attacker to conduct an arbitrary script injection attack on an affected device. The vulnerability exists because the software running on an affected device insufficiently validates user-supplied data. An attacker could exploit this vulnerability by persuading a user to click a malicious link provided to the user or through the interface of an affected device. A successful exploit could allow an attacker to execute arbitrary script code in the context of the user interface or access sensitive system-based information, which under normal circumstances should be prohibited.
The exploitability of CVE-2018-0461 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).
With low attack complexity and no required privileges, CVE-2018-0461 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.
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-2018-0461, 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-2018-0461, 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: 0.201% (probability of exploit)
EPSS Percentile: 58.57%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 41.43% of others.
