https://notcve.org/view.php?id=CVE-2020-11979
As mitigation for CVE-2020-1945 Apache Ant 1.10.8 changed the permissions of temporary files it created so that only the current user was allowed to access them. Unfortunately the fixcrlf task deleted the temporary file and created a new one without said protection, effectively nullifying the effort. This would still allow an attacker to inject modified source files into the build process. Como mitigación para CVE-2020-1945, Apache Ant versión 1.10.8, cambió los permisos de los archivos temporales que creó para que solo el usuario actual pudiera acceder a ellos. Desafortunadamente, la tarea fixcrlf eliminó el archivo temporal y creó uno nuevo sin dicha protección, anulando efectivamente el esfuerzo. • https://github.com/gradle/gradle/security/advisories/GHSA-j45w-qrgf-25vm https://lists.apache.org/thread.html/r107ea1b1a7a214bc72fe1a04207546ccef542146ae22952e1013b5cc%40%3Cdev.creadur.apache.org%3E https://lists.apache.org/thread.html/r1dc8518dc99c42ecca5ff82d0d2de64cd5d3a4fa691eb9ee0304781e%40%3Cdev.creadur.apache.org%3E https://lists.apache.org/thread.html/r2306b67f20c24942b872b0a41fbdc9330e8467388158bcd19c1094e0%40%3Cdev.creadur.apache.org%3E https://lists.apache.org/thread.html/r4ca33fad3fb39d130cda287d5a60727d9e706e6f2cf2339b95729490%40%3Cdev.creadur.apache.org%3E https • CWE-377: Insecure Temporary File CWE-379: Creation of Temporary File in Directory with Insecure Permissions •

CVSS: 7.0EPSS: 91%CPEs: 77EXPL: 12CVE-2020-9484 – tomcat: deserialization flaw in session persistence storage leading to RCE
https://notcve.org/view.php?id=CVE-2020-9484
When using Apache Tomcat versions 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54 and 7.0.0 to 7.0.103 if a) an attacker is able to control the contents and name of a file on the server; and b) the server is configured to use the PersistenceManager with a FileStore; and c) the PersistenceManager is configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker provided object to be deserialized; and d) the attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over; then, using a specifically crafted request, the attacker will be able to trigger remote code execution via deserialization of the file under their control. Note that all of conditions a) to d) must be true for the attack to succeed. Cuando se usa Apache Tomcat versiones 10.0.0-M1 hasta 10.0.0-M4, 9.0.0.M1 hasta 9.0.34, 8.5.0 hasta 8.5.54 y 7.0.0 hasta 7.0. 103, si a) un atacante es capaz de controlar el contenido y el nombre de un archivo en el servidor; y b) el servidor está configurado para usar el PersistenceManager con un FileStore; y c) el PersistenceManager está configurado con sessionAttributeValueClassNameFilter="null" (el valor predeterminado a menos que se utilice un SecurityManager) o un filtro lo suficientemente laxo como para permitir que el objeto proporcionado por el atacante sea deserializado; y d) el atacante conoce la ruta relativa del archivo desde la ubicación de almacenamiento usada por FileStore hasta el archivo sobre el que el atacante presenta control; entonces, mediante una petición específicamente diseñada, el atacante podrá ser capaz de desencadenar una ejecución de código remota mediante la deserialización del archivo bajo su control. Tome en cuenta que todas las condiciones desde la a) hasta la d) deben cumplirse para que el ataque tenga éxito. A deserialization flaw was discovered in Apache Tomcat's use of a FileStore. • https://github.com/masahiro331/CVE-2020-9484 https://github.com/IdealDreamLast/CVE-2020-9484 https://github.com/osamahamad/CVE-2020-9484-Mass-Scan https://github.com/PenTestical/CVE-2020-9484 https://github.com/AssassinUKG/CVE-2020-9484 https://github.com/RepublicR0K/CVE-2020-9484 https://github.com/anjai94/CVE-2020-9484-exploit https://github.com/ColdFusionX/CVE-2020-9484 https://github.com/VICXOR/CVE-2020-9484 https://github.com/seanachao/CVE-2020-9484 https://github& • CWE-502: Deserialization of Untrusted Data •

https://notcve.org/view.php?id=CVE-2020-1945
Apache Ant 1.1 to 1.9.14 and 1.10.0 to 1.10.7 uses the default temporary directory identified by the Java system property java.io.tmpdir for several tasks and may thus leak sensitive information. The fixcrlf and replaceregexp tasks also copy files from the temporary directory back into the build tree allowing an attacker to inject modified source files into the build process. Apache Ant versiones 1.1 hasta 1.9.14 y versiones 1.10.0 hasta 1.10.7, utiliza el directorio temporal por defecto identificado por la propiedad del sistema Java java.io.tmpdir para varias tareas y puede, por tanto, filtrar información confidencial. Las tareas fixcrlf y replaceregexp también copian los archivos desde el directorio temporal de nuevo en el árbol de compilación, lo que permite a un atacante inyectar archivos fuente modificados en el proceso de compilación. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00053.html http://www.openwall.com/lists/oss-security/2020/09/30/6 http://www.openwall.com/lists/oss-security/2020/12/06/1 https://lists.apache.org/thread.html/r0d08a96ba9de8aa435f32944e8b2867c368a518d4ff57782e3637335%40%3Cissues.hive.apache.org%3E https://lists.apache.org/thread.html/r107ea1b1a7a214bc72fe1a04207546ccef542146ae22952e1013b5cc%40%3Cdev.creadur.apache.org%3E https://lists.apache.org/thread.html/r1863b9ce4c3e4b1e5b0c671ad05545ba3eb8399616aa746af5dfe1b1%40%3Cdev.crea • CWE-377: Insecure Temporary File CWE-668: Exposure of Resource to Wrong Sphere •
