CVE-2022-44749: A directory traversal vulnerability in the ZIP archive extraction routines of KNIME Analytics Platform 3.2.0 and above can result in arbitrary files being overwritten on the user's system. This vulnerability is also known as 'Zip-Slip'. An attacker can create a KNIME workflow that, when being opened by a user, can overwrite arbitrary files that the user has write access to. It's not necessary to execute the workflow, opening the workflow is sufficient. The user will notice that something is wrong because an error is being reported but only after the files have already been written. This can impact data integrity (file contents are changed) or cause errors in other software (vital files being corrupted). It can even lead to remote code execution if executable files are being replaced and subsequently executed by the user. In all cases the attacker has to know the location of files on the user's system, though.
The exploitability of CVE-2022-44749 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-2022-44749 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-2022-44749, 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-2022-44749, 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: 0.223% (probability of exploit)
EPSS Percentile: 61.01%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 38.99% of others.
