CVE-2021-32496: SICK Visionary-S CX up version 5.21.2.29154R are vulnerable to an Inadequate Encryption Strength vulnerability concerning the internal SSH interface solely used by SICK for recovering returned devices. The use of weak ciphers make it easier for an attacker to break the security that protects information transmitted from the client to the SSH server, assuming the attacker has access to the network on which the device is connected. This can increase the risk that encryption will be compromised, leading to the exposure of sensitive user information and man-in-the-middle attacks.
The exploitability of CVE-2021-32496 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-2021-32496, 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-2021-32496, 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-2021-32496, 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: 0.06% (probability of exploit)
EPSS Percentile: 28.47%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 71.53% of others.
