CVE-2017-2348: The Juniper Enhanced jdhcpd daemon may experience high CPU utilization, or crash and restart upon receipt of an invalid IPv6 UDP packet. Both high CPU utilization and repeated crashes of the jdhcpd daemon can result in a denial of service as DHCP service is interrupted. No other Juniper Networks products or platforms are affected by this issue. Affected releases are Juniper Networks Junos OS 14.1X53 prior to 14.1X53-D12, 14.1X53-D38, 14.1X53-D40 on QFX, EX, QFabric System; 15.1 prior to 15.1F2-S18, 15.1R4 on all products and platforms; 15.1X49 prior to 15.1X49-D80 on SRX; 15.1X53 prior to 15.1X53-D51, 15.1X53-D60 on NFX, QFX, EX.
The exploitability of CVE-2017-2348 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-2017-2348 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-2017-2348, 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-2017-2348, 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: 0.083% (probability of exploit)
EPSS Percentile: 38.2%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 61.8% of others.
