CVE-2021-45105 5 Apache, Debian, Netapp and 2 more 121 Log4j, Debian Linux, Cloud Manager and 118 more 2024-11-21 4.3 MEDIUM 5.9 MEDIUM
Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3 and 2.3.1) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0, 2.12.3, and 2.3.1.
CVE-2021-45046 7 Apache, Cvat, Debian and 4 more 61 Log4j, Computer Vision Annotation Tool, Debian Linux and 58 more 2024-11-21 5.1 MEDIUM 9.0 CRITICAL
It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-default configurations. This could allows attackers with control over Thread Context Map (MDC) input data when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some environments and local code execution in all environments. Log4j 2.16.0 (Java 8) and 2.12.2 (Java 7) fix this issue by removing support for message lookup patterns and disabling JNDI functionality by default.
CVE-2021-45029 1 Apache 1 Shenyu 2024-11-21 7.5 HIGH 9.8 CRITICAL
Groovy Code Injection & SpEL Injection which lead to Remote Code Execution. This issue affected Apache ShenYu 2.4.0 and 2.4.1.
CVE-2021-44832 5 Apache, Cisco, Debian and 2 more 22 Log4j, Cloudcenter, Debian Linux and 19 more 2024-11-21 8.5 HIGH 6.6 MEDIUM
Apache Log4j2 versions 2.0-beta7 through 2.17.0 (excluding security fix releases 2.3.2 and 2.12.4) are vulnerable to a remote code execution (RCE) attack when a configuration uses a JDBC Appender with a JNDI LDAP data source URI when an attacker has control of the target LDAP server. This issue is fixed by limiting JNDI data source names to the java protocol in Log4j2 versions 2.17.1, 2.12.4, and 2.3.2.
CVE-2021-44791 1 Apache 1 Druid 2024-11-21 4.3 MEDIUM 6.1 MEDIUM
In Apache Druid 0.22.1 and earlier, certain specially-crafted links result in unescaped URL parameters being sent back in HTML responses. This makes it possible to execute reflected XSS attacks.
CVE-2021-44790 7 Apache, Apple, Debian and 4 more 14 Http Server, Mac Os X, Macos and 11 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier.
CVE-2021-44759 2 Apache, Debian 2 Traffic Server, Debian Linux 2024-11-21 6.8 MEDIUM 8.1 HIGH
Improper Authentication vulnerability in TLS origin validation of Apache Traffic Server allows an attacker to create a man in the middle attack. This issue affects Apache Traffic Server 8.0.0 to 8.1.0.
CVE-2021-44549 1 Apache 1 Sling Commons Messaging Mail 2024-11-21 5.8 MEDIUM 7.4 HIGH
Apache Sling Commons Messaging Mail provides a simple layer on top of JavaMail/Jakarta Mail for OSGi to send mails via SMTPS. To reduce the risk of "man in the middle" attacks additional server identity checks must be performed when accessing mail servers. For compatibility reasons these additional checks are disabled by default in JavaMail/Jakarta Mail. The SimpleMailService in Apache Sling Commons Messaging Mail 1.0 lacks an option to enable these checks for the shared mail session. A user could enable these checks nevertheless by accessing the session via the message created by SimpleMessageBuilder and setting the property mail.smtps.ssl.checkserveridentity to true. Apache Sling Commons Messaging Mail 2.0 adds support for enabling server identity checks and these checks are enabled by default. - https://javaee.github.io/javamail/docs/SSLNOTES.txt - https://javaee.github.io/javamail/docs/api/com/sun/mail/smtp/package-summary.html - https://github.com/eclipse-ee4j/mail/issues/429
CVE-2021-44548 2 Apache, Microsoft 2 Solr, Windows 2024-11-21 6.8 MEDIUM 9.8 CRITICAL
An Improper Input Validation vulnerability in DataImportHandler of Apache Solr allows an attacker to provide a Windows UNC path resulting in an SMB network call being made from the Solr host to another host on the network. If the attacker has wider access to the network, this may lead to SMB attacks, which may result in: * The exfiltration of sensitive data such as OS user hashes (NTLM/LM hashes), * In case of misconfigured systems, SMB Relay Attacks which can lead to user impersonation on SMB Shares or, in a worse-case scenario, Remote Code Execution This issue affects all Apache Solr versions prior to 8.11.1. This issue only affects Windows.
CVE-2021-44521 1 Apache 1 Cassandra 2024-11-21 8.5 HIGH 9.1 CRITICAL
When running Apache Cassandra with the following configuration: enable_user_defined_functions: true enable_scripted_user_defined_functions: true enable_user_defined_functions_threads: false it is possible for an attacker to execute arbitrary code on the host. The attacker would need to have enough permissions to create user defined functions in the cluster to be able to exploit this. Note that this configuration is documented as unsafe, and will continue to be considered unsafe after this CVE.
CVE-2021-44451 1 Apache 1 Superset 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
Apache Superset up to and including 1.3.2 allowed for registered database connections password leak for authenticated users. This information could be accessed in a non-trivial way. Users should upgrade to Apache Superset 1.4.0 or higher.
CVE-2021-44228 12 Apache, Apple, Bentley and 9 more 157 Log4j, Xcode, Synchro and 154 more 2024-11-21 9.3 HIGH 10.0 CRITICAL
Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects.
CVE-2021-44224 6 Apache, Apple, Debian and 3 more 12 Http Server, Mac Os X, Macos and 9 more 2024-11-21 6.4 MEDIUM 8.2 HIGH
A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included).
CVE-2021-44145 1 Apache 1 Nifi 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
In the TransformXML processor of Apache NiFi before 1.15.1 an authenticated user could configure an XSLT file which, if it included malicious external entity calls, may reveal sensitive information.
CVE-2021-44140 1 Apache 1 Jspwiki 2024-11-21 6.4 MEDIUM 9.1 CRITICAL
Remote attackers may delete arbitrary files in a system hosting a JSPWiki instance, versions up to 2.11.0.M8, by using a carefuly crafted http request on logout, given that those files are reachable to the user running the JSPWiki instance. Apache JSPWiki users should upgrade to 2.11.0 or later.
CVE-2021-44040 2 Apache, Debian 2 Traffic Server, Debian Linux 2024-11-21 5.0 MEDIUM 7.5 HIGH
Improper Input Validation vulnerability in request line parsing of Apache Traffic Server allows an attacker to send invalid requests. This issue affects Apache Traffic Server 8.0.0 to 8.1.3 and 9.0.0 to 9.1.1.
CVE-2021-43999 1 Apache 1 Guacamole 2024-11-21 6.0 MEDIUM 8.8 HIGH
Apache Guacamole 1.2.0 and 1.3.0 do not properly validate responses received from a SAML identity provider. If SAML support is enabled, this may allow a malicious user to assume the identity of another Guacamole user.
CVE-2021-43980 2 Apache, Debian 2 Tomcat, Debian Linux 2024-11-21 N/A 3.7 LOW
The simplified implementation of blocking reads and writes introduced in Tomcat 10 and back-ported to Tomcat 9.0.47 onwards exposed a long standing (but extremely hard to trigger) concurrency bug in Apache Tomcat 10.1.0 to 10.1.0-M12, 10.0.0-M1 to 10.0.18, 9.0.0-M1 to 9.0.60 and 8.5.0 to 8.5.77 that could cause client connections to share an Http11Processor instance resulting in responses, or part responses, to be received by the wrong client.
CVE-2021-43557 1 Apache 1 Apisix 2024-11-21 5.0 MEDIUM 7.5 HIGH
The uri-block plugin in Apache APISIX before 2.10.2 uses $request_uri without verification. The $request_uri is the full original request URI without normalization. This makes it possible to construct a URI to bypass the block list on some occasions. For instance, when the block list contains "^/internal/", a URI like `//internal/` can be used to bypass it. Some other plugins also have the same issue. And it may affect the developer's custom plugin.
CVE-2021-43410 1 Apache 1 Airavata Django Portal 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
Apache Airavata Django Portal allows CRLF log injection because of lack of escaping log statements. In particular, some HTTP request parameters are logged without first being escaped. Versions affected: master branch before commit 3c5d8c7 [1] of airavata-django-portal [1] https://github.com/apache/airavata-django-portal/commit/3c5d8c72bfc3eb0af8693a655a5d60f9273f8170
