The issue was addressed in a series of patches in versions 0.25.3, 0.25.4 and 0.25.5. This most impacts scenarios where non-trusted users are given permission to upload images in any area of the application. They would then have the permissions of the PHP process. Unmarshalling untrusted data can lead to security flaws of RCE.īookStack before version 0.25.5 has a vulnerability where a user could upload PHP files through image upload functions, which would allow them to execute code on the host system remotely. SnakeYAML allows to unmarshal data to a Java type By using the YAML tag. In Apache ShardingSphere(incubator) 4.0.0-RC3 and 4.0.0, the ShardingSphere's web console uses the SnakeYAML library for parsing YAML inputs to load datasource configuration.
Please note that some of the information in the bulletin is compiled from external, open-source reports and is not a direct result of CISA analysis. Patch information is provided when available. This information may include identifying information, values, definitions, and related links. Low: vulnerabilities with a CVSS base score of 0.0–3.9Įntries may include additional information provided by organizations and efforts sponsored by CISA.Medium: vulnerabilities with a CVSS base score of 4.0–6.9.High: vulnerabilities with a CVSS base score of 7.0–10.0.The division of high, medium, and low severities correspond to the following scores: Vulnerabilities are based on the Common Vulnerabilities and Exposures (CVE) vulnerability naming standard and are organized according to severity, determined by the Common Vulnerability Scoring System (CVSS) standard. Please visit NVD for updated vulnerability entries, which include CVSS scores once they are available.
In some cases, the vulnerabilities in the bulletin may not yet have assigned CVSS scores. The CISA Vulnerability Bulletin provides a summary of new vulnerabilities that have been recorded by the National Institute of Standards and Technology (NIST) National Vulnerability Database (NVD) in the past week.
