CVE-2023-6481 qos vulnerability CVSS: 0 04 Dec 2023, 09:15 UTC

A serialization vulnerability in logback receiver component part of logback version 1.4.13, 1.3.13 and 1.2.12 allows an attacker to mount a Denial-Of-Service attack by sending poisoned data.

CVE-2023-6378 qos vulnerability CVSS: 0 29 Nov 2023, 12:15 UTC

A serialization vulnerability in logback receiver component part of logback version 1.4.11 allows an attacker to mount a Denial-Of-Service attack by sending poisoned data.

CVE-2022-23307 qos vulnerability CVSS: 9.0 18 Jan 2022, 16:15 UTC

CVE-2020-9493 identified a deserialization issue that was present in Apache Chainsaw. Prior to Chainsaw V2.0 Chainsaw was a component of Apache Log4j 1.2.x where the same issue exists.

CVE-2022-23305 qos vulnerability CVSS: 6.8 18 Jan 2022, 16:15 UTC

By design, the JDBCAppender in Log4j 1.2.x accepts an SQL statement as a configuration parameter where the values to be inserted are converters from PatternLayout. The message converter, %m, is likely to always be included. This allows attackers to manipulate the SQL by entering crafted strings into input fields or headers of an application that are logged allowing unintended SQL queries to be executed. Note this issue only affects Log4j 1.x when specifically configured to use the JDBCAppender, which is not the default. Beginning in version 2.0-beta8, the JDBCAppender was re-introduced with proper support for parameterized SQL queries and further customization over the columns written to in logs. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions.

CVE-2022-23302 qos vulnerability CVSS: 6.0 18 Jan 2022, 16:15 UTC

JMSSink in all versions of Log4j 1.x is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration or if the configuration references an LDAP service the attacker has access to. The attacker can provide a TopicConnectionFactoryBindingName configuration causing JMSSink to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-4104. Note this issue only affects Log4j 1.x when specifically configured to use JMSSink, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions.

CVE-2021-42550 qos vulnerability CVSS: 8.5 16 Dec 2021, 19:15 UTC

In logback version 1.2.7 and prior versions, an attacker with the required privileges to edit configurations files could craft a malicious configuration allowing to execute arbitrary code loaded from LDAP servers.

CVE-2020-9493 qos vulnerability CVSS: 6.8 16 Jun 2021, 08:15 UTC

A deserialization flaw was found in Apache Chainsaw versions prior to 2.1.0 which could lead to malicious code execution.

CVE-2020-9488 qos vulnerability CVSS: 4.3 27 Apr 2020, 16:15 UTC

Improper validation of certificate with host mismatch in Apache Log4j SMTP appender. This could allow an SMTPS connection to be intercepted by a man-in-the-middle attack which could leak any log messages sent through that appender. Fixed in Apache Log4j 2.12.3 and 2.13.1

CVE-2018-8088 qos vulnerability CVSS: 7.5 20 Mar 2018, 16:29 UTC

org.slf4j.ext.EventData in the slf4j-ext module in QOS.CH SLF4J before 1.8.0-beta2 allows remote attackers to bypass intended access restrictions via crafted data. EventData in the slf4j-ext module in QOS.CH SLF4J, has been fixed in SLF4J versions 1.7.26 later and in the 2.0.x series.

CVE-2017-5929 qos vulnerability CVSS: 7.5 13 Mar 2017, 06:59 UTC

QOS.ch Logback before 1.2.0 has a serialization vulnerability affecting the SocketServer and ServerSocketReceiver components.
