CVE-2015-8214: A vulnerability has been identified in SIMATIC NET CP 342-5 (incl. SIPLUS variants) (All versions), SIMATIC NET CP 343-1 Advanced (incl. SIPLUS variants) (All versions < V3.0.44), SIMATIC NET CP 343-1 Lean (incl. SIPLUS variants) (All versions < V3.1.1), SIMATIC NET CP 343-1 Standard (incl. SIPLUS variants) (All versions < V3.1.1), SIMATIC NET CP 443-1 Advanced (incl. SIPLUS variants) (All versions < V3.2.9), SIMATIC NET CP 443-1 Standard (incl. SIPLUS variants) (All versions < V3.2.9), SIMATIC NET CP 443-5 Basic (incl. SIPLUS variants) (All versions), SIMATIC NET CP 443-5 Extended (All versions), TIM 3V-IE / TIM 3V-IE Advanced (incl. SIPLUS NET variants) (All versions < V2.6.0), TIM 3V-IE DNP3 (incl. SIPLUS NET variants) (All versions < V3.1.0), TIM 4R-IE (incl. SIPLUS NET variants) (All versions < V2.6.0), TIM 4R-IE DNP3 (incl. SIPLUS NET variants) (All versions < V3.1.0). The implemented access protection level enforcement of the affected communication processors (CP) could possibly allow unauthenticated users to perform administrative operations on the CPs if network access (port 102/TCP) is available and the CPs' configuration was stored on their corresponding CPUs.
The exploitability of CVE-2015-8214 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-2015-8214 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-2015-8214, 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-2015-8214, 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: 0.335% (probability of exploit)
EPSS Percentile: 71.47%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 28.53% of others.
