Apache log4net: NUL character truncates EventLogAppender records

Improper Neutralization of Null Byte or NUL Character vulnerability in the EventLogAppender of Apache log4net. A NUL character in logged content ended the Windows Event Log record at that point, so everything the layout rendered after it, including exception text and trailing fields, was silently not stored. A party whose data reaches a log message could hide the rest of that record. Only applications on Windows that use EventLogAppender are affected. This issue affects Apache log4net: from 1.2.9 before 3.5.0. Users are recommended to upgrade to version 3.5.0, which fixes the issue.

Apache log4net: Unencodable content discards a whole SmtpPickupDirAppender batch

Improper Handling of Unicode Encoding vulnerability in the SmtpPickupDirAppender of Apache log4net. Content that the mail file writer cannot encode, such as an unpaired UTF-16 surrogate, made the write throw. Every buffered event in the batch was discarded, not only the one carrying the content, and a truncated mail could be left in the pickup directory. A party whose data reaches a log message could suppress the records of other events. Only applications that use SmtpPickupDirAppender are affected. This issue affects Apache log4net: from 1.2.9 before 3.5.0. Users are recommended to upgrade to version 3.5.0, which fixes the issue.

Apache log4net: Request validation failure drops the event in the aspnet-request converter

Improper Handling of Exceptional Conditions vulnerability in the aspnet-request pattern converter of Apache log4net. Reading request parameters triggers ASP.NET request validation, so a request carrying content such as markup made the layout throw and the appender discarded the whole event. A sender could suppress the log record of their own request. Only applications on ASP.NET for .NET Framework whose layout uses %aspnet-request are affected. This issue affects Apache log4net: from 1.2.11 before 3.5.0. Users are recommended to upgrade to version 3.5.0, which fixes the issue.

Insufficient Logging vulnerability in the EventLogAppender of Apache log4net. Long messages were truncated to a fixed size that exceeds what the Windows Event Log accepts once the log and source names are counted, and the event log then stored nothing and reported nothing. A party whose data reaches a log message could suppress the whole record by making it long enough. Only applications on Windows that use EventLogAppender are affected. This issue affects Apache log4net: from 1.2.9 before 3.5.0. Users are recommended to upgrade to version 3.5.0, which fixes the issue.

Apache log4net: RemoteSyslogAppender silently deletes non-ASCII content

Improper Encoding or Escaping of Output vulnerability in the RemoteSyslogAppender of Apache log4net. Every character outside visible ASCII and space was removed from the record instead of being escaped, so non-ASCII text and control characters such as tabs disappeared without notice. A party whose data reaches a log message could make a distinct value look identical in the record, for example a user name holding a zero-width space logged as admin. Only applications that use RemoteSyslogAppender are affected. This issue affects Apache log4net: from 1.2.12 before 3.5.0. Users are recommended to upgrade to version 3.5.0, which fixes the issue.

Improper neutralization of input during web page generation ('cross-site scripting') vulnerability in Apache Commons BCEL. This only happens when you're using Class2HTML to generate webpages for possibly-attacker-controlled class files, where Class2HTML emitters write attacker class-file strings into HTML unescaped (stored XSS in reports). This issue affects Apache Commons BCEL: before 6.13.0. Users are recommended to upgrade to version 6.13.0, which fixes the issue.

Apache YuniKorn: Admission control bypass via workload UPDATE operation

Apache YuniKorn 1.9.0 and earlier does not implement label and user annotation checks for workload UPDATE action bypassing all checks. Workloads in YuniKorn are defined as the following Kubernetes objects: "deployments", "replicasets", "statefulsets", "daemonsets", "jobs", "cronjobs". The CREATE action correctly enforces the checks for all object types. The bypass allows any user to specify an arbitrary user info annotation. The same bypass also allows changing the application ID for the workload. The combination of the two applied in one UPDATE could allow access to a queue that the user normally would not have access to. Quota usage for the queue might be impacted if the application runs in the incorrect queue. User based quota enforcement is also based on the user annotation. User quota tracking could be side stepped even if the application runs in the correct queue. Users are recommended to upgrade to version 1.10.0, which fixes this issue.

Apache YuniKorn: Admission control bypass via system label forgery

Apache YuniKorn 1.9.0 and earlier allows bypassing the check for the user annotation by setting a secondary label on the pod. If the pod has the label 'app=yunikorn' the checks limiting the user annotation content are not run. The label is used to identify the YuniKorn application itself in the deployments. The bypass allows any user to specify an arbitrary user info annotation. The arbitrary user information could allow access to a queue that the user normally would not have access to. Quota usage for the queue might be impacted if the application runs in the incorrect queue. User based quota enforcement is also based on the user annotation. User quota tracking could be side stepped even if the application runs in the correct queue. Users are recommended to upgrade to version 1.10.0, which fixes this issue.

Apache DolphinScheduler: Missing Authorization Checks Allow Disclosure of Data Source Information and Passwords

An authorization vulnerability in Apache DolphinScheduler allows authenticated users to obtain information about data sources they are not authorized to access through the /unauth-datasource and /authed-datasource endpoints. These endpoints fail to enforce the required data source access controls and return sensitive connection information, including data source passwords. As a result, an authenticated user without permission to access a data source can retrieve its connection details and credentials. Successful exploitation exposes sensitive data source information and may enable unauthorized access to the underlying databases using the disclosed credentials. This issue affects Apache DolphinScheduler: before 3.4.3. Users are recommended to upgrade to version 3.4.3, which fixes the issue.

Incomplete Cleanup vulnerability in Apache Tomcat. The internal fork of Commons FileUpload packaged with Apache Tomcat 9.0.70 through 9.0.80 and 8.5.85 through 8.5.93 included an unreleased, in progress refactoring that exposed a potential denial of service on Windows if a web application opened a stream for an uploaded file but failed to close the stream. The file would never be deleted from disk creating the possibility of an eventual denial of service due to the disk being full. Other, EOL versions may also be affected. Users are recommended to upgrade to version 9.0.81 onwards or 8.5.94 onwards, which fixes the issue.
