CVE-2018-0058: Receipt of a specially crafted IPv6 exception packet may be able to trigger a kernel crash (vmcore), causing the device to reboot. The issue is specific to the processing of Broadband Edge (BBE) client route processing on MX Series subscriber management platforms, introduced by the Tomcat (Next Generation Subscriber Management) functionality in Junos OS 15.1. This issue affects no other platforms or configurations. Affected releases are Juniper Networks Junos OS: 15.1 versions prior to 15.1R7-S2, 15.1R8 on MX Series; 16.1 versions prior to 16.1R4-S11, 16.1R7-S2, 16.1R8 on MX Series; 16.2 versions prior to 16.2R3 on MX Series; 17.1 versions prior to 17.1R2-S9, 17.1R3 on MX Series; 17.2 versions prior to 17.2R2-S6, 17.2R3 on MX Series; 17.3 versions prior to 17.3R2-S4, 17.3R3-S2, 17.3R4 on MX Series; 17.4 versions prior to 17.4R2 on MX Series; 18.1 versions prior to 18.1R2-S3, 18.1R3 on MX Series; 18.2 versions prior to 18.2R1-S1, 18.2R2 on MX Series.
The exploitability of CVE-2018-0058 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-2018-0058 presents a challenge to exploit due to its high attack complexity, but the absence of privilege requirements still makes it a viable target for skilled attackers. A thorough security review is advised.
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-2018-0058, 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-2018-0058, 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: 0.102% (probability of exploit)
EPSS Percentile: 43.72%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 56.28% of others.
