CVE-2016-10041: An issue was discovered in Sprecher Automation SPRECON-E Service Program before 3.43 SP0. Under certain preconditions, it is possible to execute telegram simulation as a non-admin user. As prerequisites, a user must have created an online-connection, validly authenticated and authorized as administrator, and executed telegram simulation. After that, the online-connection must have been closed. Incorrect caching of client data then may lead to privilege escalation, where a subsequently acting non-admin user is permitted to do telegram simulation. In order to exploit this vulnerability, a potential attacker would need to have both a valid engineering-account in the SPRECON RBAC system as well as access to a service/maintenance computer with SPRECON-E Service Program running. Additionally, a valid admin-user must have closed the service connection beforehand without closing the program, having executed telegram simulation; the attacker then has access to the running software instance. Hence, there is no risk from external attackers.
The exploitability of CVE-2016-10041 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).
This vulnerability, CVE-2016-10041, requires a high level of attack complexity and low privileges, making it difficult but not impossible to exploit. Organizations should ensure robust security configurations to mitigate risks.
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-2016-10041, 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-2016-10041, 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: 0.097% (probability of exploit)
EPSS Percentile: 42.69%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 57.31% of others.
