CVE-2023-50298 – Apache Solr: Solr can expose ZooKeeper credentials via Streaming Expressions
https://notcve.org/view.php?id=CVE-2023-50298
Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Solr.This issue affects Apache Solr: from 6.0.0 through 8.11.2, from 9.0.0 before 9.4.1. Solr Streaming Expressions allows users to extract data from other Solr Clouds, using a "zkHost" parameter. When original SolrCloud is setup to use ZooKeeper credentials and ACLs, they will be sent to whatever "zkHost" the user provides. An attacker could setup a server to mock ZooKeeper, that accepts ZooKeeper requests with credentials and ACLs and extracts the sensitive information, then send a streaming expression using the mock server's address in "zkHost". Streaming Expressions are exposed via the "/streaming" handler, with "read" permissions. Users are recommended to upgrade to version 8.11.3 or 9.4.1, which fix the issue. From these versions on, only zkHost values that have the same server address (regardless of chroot), will use the given ZooKeeper credentials and ACLs when connecting. Exposición de información confidencial a una vulnerabilidad de actor no autorizado en Apache Solr. Este problema afecta a Apache Solr: desde 6.0.0 hasta 8.11.2, desde 9.0.0 antes de 9.4.1. Solr Streaming Expressions permite a los usuarios extraer datos de otras nubes Solr, utilizando un parámetro "zkHost". Cuando SolrCloud original está configurado para usar las credenciales y ACL de ZooKeeper, se enviarán a cualquier "zkHost" que proporcione el usuario. • http://www.openwall.com/lists/oss-security/2024/02/09/2 http://www.openwall.com/lists/oss-security/2024/02/09/3 https://solr.apache.org/security.html#cve-2023-50298-apache-solr-can-expose-zookeeper-credentials-via-streaming-expressions • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-922: Insecure Storage of Sensitive Information •
CVE-2023-50386 – Apache Solr: Backup/Restore APIs allow for deployment of executables in malicious ConfigSets
https://notcve.org/view.php?id=CVE-2023-50386
Improper Control of Dynamically-Managed Code Resources, Unrestricted Upload of File with Dangerous Type, Inclusion of Functionality from Untrusted Control Sphere vulnerability in Apache Solr.This issue affects Apache Solr: from 6.0.0 through 8.11.2, from 9.0.0 before 9.4.1. In the affected versions, Solr ConfigSets accepted Java jar and class files to be uploaded through the ConfigSets API. When backing up Solr Collections, these configSet files would be saved to disk when using the LocalFileSystemRepository (the default for backups). If the backup was saved to a directory that Solr uses in its ClassPath/ClassLoaders, then the jar and class files would be available to use with any ConfigSet, trusted or untrusted. When Solr is run in a secure way (Authorization enabled), as is strongly suggested, this vulnerability is limited to extending the Backup permissions with the ability to add libraries. Users are recommended to upgrade to version 8.11.3 or 9.4.1, which fix the issue. In these versions, the following protections have been added: * Users are no longer able to upload files to a configSet that could be executed via a Java ClassLoader. * The Backup API restricts saving backups to directories that are used in the ClassLoader. Control inadecuado de recursos de código administrados dinámicamente, carga sin restricciones de archivos con tipos peligrosos, inclusión de funcionalidad de vulnerabilidad de esfera de control no confiable en Apache Solr. Este problema afecta a Apache Solr: desde 6.0.0 hasta 8.11.2, desde 9.0.0 antes de 9.4 .1. En las versiones afectadas, Solr ConfigSets aceptó la carga de archivos jar y de clase de Java a través de la API de ConfigSets. Al realizar una copia de seguridad de las colecciones de Solr, estos archivos de configuración se guardarán en el disco cuando se utilice LocalFileSystemRepository (el valor predeterminado para las copias de seguridad). • http://www.openwall.com/lists/oss-security/2024/02/09/1 https://solr.apache.org/security.html#cve-2023-50386-apache-solr-backuprestore-apis-allow-for-deployment-of-executables-in-malicious-configsets • CWE-434: Unrestricted Upload of File with Dangerous Type CWE-913: Improper Control of Dynamically-Managed Code Resources •
CVE-2023-50290 – Apache Solr: Host environment variables are published via the Metrics API
https://notcve.org/view.php?id=CVE-2023-50290
Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Solr. The Solr Metrics API publishes all unprotected environment variables available to each Apache Solr instance. Users are able to specify which environment variables to hide, however, the default list is designed to work for known secret Java system properties. Environment variables cannot be strictly defined in Solr, like Java system properties can be, and may be set for the entire host, unlike Java system properties which are set per-Java-proccess. The Solr Metrics API is protected by the "metrics-read" permission. Therefore, Solr Clouds with Authorization setup will only be vulnerable via users with the "metrics-read" permission. This issue affects Apache Solr: from 9.0.0 before 9.3.0. Users are recommended to upgrade to version 9.3.0 or later, in which environment variables are not published via the Metrics API.

CVE-2023-44487 – HTTP/2 Rapid Reset Attack Vulnerability
https://notcve.org/view.php?id=CVE-2023-44487
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. El protocolo HTTP/2 permite una denegación de servicio (consumo de recursos del servidor) porque la cancelación de solicitudes puede restablecer muchas transmisiones rápidamente, como se explotó en la naturaleza entre agosto y octubre de 2023. A flaw was found in handling multiplexed streams in the HTTP/2 protocol. A client can repeatedly make a request for a new multiplex stream and immediately send an RST_STREAM frame to cancel it. This creates extra work for the server setting up and tearing down the streams while not hitting any server-side limit for the maximum number of active streams per connection, resulting in a denial of service due to server resource consumption. • https://github.com/imabee101/CVE-2023-44487 https://github.com/studiogangster/CVE-2023-44487 https://github.com/bcdannyboy/CVE-2023-44487 https://github.com/sigridou/CVE-2023-44487- https://github.com/ByteHackr/CVE-2023-44487 https://github.com/ReToCode/golang-CVE-2023-44487 http://www.openwall.com/lists/oss-security/2023/10/13/4 http://www.openwall.com/lists/oss-security/2023/10/13/9 http://www.openwall.com/lists/oss-security/2023/10/18/4 http://www. • CWE-400: Uncontrolled Resource Consumption •
CVE-2021-44548 – Apache Solr information disclosure vulnerability through DataImportHandler
https://notcve.org/view.php?id=CVE-2021-44548
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. Una vulnerabilidad de Comprobación de Entrada Inapropiada en DataImportHandler de Apache Solr permite a un atacante proporcionar una ruta UNC de Windows que resulta en una llamada de red SMB que es hecha desde el host Solr a otro host en la red. Si el atacante presenta un acceso más amplio a la red, esto puede conllevar a ataques SMB, que pueden resultar en: * La exfiltración de datos confidenciales como los hashes de usuario del Sistema Operativo (hashes NTLM/LM), * En caso de sistemas configurados inapropiadamente, ataques de retransmisión SMB que pueden conllevar a una suplantación de usuarios en recursos compartidos SMB o, en el peor de los casos, una ejecución de código remota. • https://security.netapp.com/advisory/ntap-20220114-0005 https://solr.apache.org/security.html#cve-2021-44548-apache-solr-information-disclosure-vulnerability-through-dataimporthandler • CWE-20: Improper Input Validation CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-40: Path Traversal: '\\UNC\share\name\' (Windows UNC Share) •
