CVE-2023-5562: An unsafe default configuration in KNIME Analytics Platform before 5.2.0 allows for a cross-site scripting attack. When KNIME Analytics Platform is used as an executor for either KNIME Server or KNIME Business Hub several JavaScript-based view nodes do not sanitize the data that is displayed by default. If the data to be displayed contains JavaScript this code is executed in the browser and can perform any operations that the current user is allowed to perform silently. KNIME Analytics Platform already has configuration options with which sanitization of data can be actived, see https://docs.knime.com/latest/webportal_admin_guide/index.html#html-sanitization-webportal https://docs.knime.com/latest/webportal_admin_guide/index.html#html-sanitization-webportal . However, these are off by default which allows for cross-site scripting attacks. KNIME Analytics Platform 5.2.0 will enable sanitization by default. For all previous releases we recommend users to add the corresponding settings to the executor's knime.ini.
The exploitability of CVE-2023-5562 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-2023-5562 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-2023-5562, 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-2023-5562, 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: 0.063% (probability of exploit)
EPSS Percentile: 30.42%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 69.58% of others.
