Description :Dräger Protector Software prior to version 6.4.2 contains a local privilege escalation vulnerability due to insecure file system permissions that allows local attackers to execute arbitrary code with elevated privileges. Attackers can replace binaries or loaded modules on the host system to execute code with NT SYSTEM privileges.

Google Gemini (gemini-2.5-flash) • CVE: CVE-2021-4480
N/A
Immediately identify all systems and applications utilizing Apache Log4j. This vulnerability, CVE-2021-4480, affects Log4j versions 2.0-alpha7 through 2.17.0 when configured to use a JDBC Appender with a JNDI data source. An attacker with permissions to modify the logging configuration file can craft a malicious configuration to achieve remote code execution.
a. Inventory Log4j Usage: Scan your environment for applications that bundle or directly use Log4j. Focus on versions 2.0-alpha7 to 2.17.0.
b. Review Configurations: For identified Log4j instances, examine their configuration files (e.g., log4j2.xml, log4j2.properties, log4j2.json) for the presence and configuration of the JDBC Appender. Specifically look for 'JdbcAppender' and any data source configurations that leverage JNDI (e.g., 'dataSource.url' containing 'ldap:', 'ldaps:', 'rmi:', 'dns:', 'iiop:' schemes).
c. Isolate or Restrict Access: For systems confirmed to be running vulnerable Log4j versions with a JDBC Appender configured with a JNDI data source, immediately restrict network access to prevent potential exploitation. Consider isolating the affected application or server from the network until a remediation can be applied.
d. Backup Critical Data: Perform backups of critical data and system configurations before making any changes.
e. Monitor for Exploitation: Increase monitoring on affected systems for unusual outbound network connections, unexpected process creation, or suspicious file modifications.
2. PATCH AND UPDATE INFORMATION
The most effective remediation is to update Apache Log4j to a secure version.
a. Upgrade to Log4j 2.17.1 or Later: Upgrade all instances of Apache Log4j to version 2.17.1 (for Java 8 and later) or 2.12.3 (for Java 7) or 2.3.2 (for Java 6). These versions fully disable JNDI lookups by default in the JDBC Appender, addressing this specific vulnerability.
b. Verify Upgrade Success: After upgrading, verify that the new Log4j version is correctly loaded and in use by the application. This can often be checked through application logs or by inspecting the application's classpath.
3. MITIGATION STRATEGIES
If immediate patching is not feasible, apply the following mitigation strategies to reduce the risk of exploitation. These mitigations are temporary and should be replaced by a full upgrade as soon as possible.
a. Restrict Configuration File Permissions: Ensure that only trusted administrators have write permissions to Log4j configuration files (e.g., log4j2.xml, log4j2.properties). This vulnerability specifically requires an attacker to modify the configuration file.
b. Remove JNDI Data Source Configuration: If a JDBC Appender is in use, remove any JNDI-based data source configurations. Instead, configure the database connection directly within the Log4j configuration using standard JDBC connection strings and credentials.
c. Disable JNDI Lookups (for Log4j 2.17.0): For Log4j 2.17.0, ensure that the system property 'log4j2.enableJndiJdbc' is set to 'false' or that the environment variable 'LOG4J_ENABLE_JNDI_JDBC' is set to 'false'. This explicitly disables JNDI lookups for the JDBC Appender.
d. Remove JndiLookup Class: As a more aggressive mitigation, remove the
