CVE-2018-4832: A vulnerability has been identified in OpenPCS 7 V7.1 and earlier (All versions), OpenPCS 7 V8.0 (All versions), OpenPCS 7 V8.1 (All versions < V8.1 Upd5), OpenPCS 7 V8.2 (All versions), OpenPCS 7 V9.0 (All versions < V9.0 Upd1), SIMATIC BATCH V7.1 and earlier (All versions), SIMATIC BATCH V8.0 (All versions < V8.0 SP1 Upd21), SIMATIC BATCH V8.1 (All versions < V8.1 SP1 Upd16), SIMATIC BATCH V8.2 (All versions < V8.2 Upd10), SIMATIC BATCH V9.0 (All versions < V9.0 SP1), SIMATIC NET PC Software V14 (All versions < V14 SP1 Update 14), SIMATIC NET PC Software V15 (All versions < 15 SP1), SIMATIC PCS 7 V7.1 and earlier (All versions), SIMATIC PCS 7 V8.0 (All versions), SIMATIC PCS 7 V8.1 (All versions), SIMATIC PCS 7 V8.2 (All versions < V8.2 SP1), SIMATIC PCS 7 V9.0 (All versions < V9.0 SP1), SIMATIC Route Control V7.1 and earlier (All versions), SIMATIC Route Control V8.0 (All versions), SIMATIC Route Control V8.1 (All versions), SIMATIC Route Control V8.2 (All versions), SIMATIC Route Control V9.0 (All versions < V9.0 Upd1), SIMATIC WinCC Runtime Professional V13 (All versions < V13 SP2 Upd2), SIMATIC WinCC Runtime Professional V14 (All versions < V14 SP1 Upd5), SIMATIC WinCC V7.2 and earlier (All versions < WinCC 7.2 Upd 15), SIMATIC WinCC V7.3 (All versions < WinCC 7.3 Upd 16), SIMATIC WinCC V7.4 (All versions < V7.4 SP1 Upd 4), SPPA-T3000 Application Server (All versions < Service Pack R8.2 SP2). Specially crafted messages sent to the RPC service of the affected products could cause a Denial-of-Service condition on the remote and local communication functionality of the affected products. A reboot of the system is required to recover the remote and local communication functionality. Please note that an attacker needs to have network access to the Application Server in order to exploit this vulnerability. At the time of advisory publication no public exploitation of this security vulnerability was known.
The exploitability of CVE-2018-4832 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-2018-4832 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-2018-4832, 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-2018-4832, 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: 0.412% (probability of exploit)
EPSS Percentile: 74.18%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 25.819999999999993% of others.
