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 •

In Wireshark 3.2.0 to 3.2.3, 3.0.0 to 3.0.10, and 2.6.0 to 2.6.16, the NFS dissector could crash. This was addressed in epan/dissectors/packet-nfs.c by preventing excessive recursion, such as for a cycle in the directory graph on a filesystem. En Wireshark versiones 3.2.0 hasta 3.2.3, 3.0.0 hasta 3.0.10 y 2.6.0 hasta 2.6.16, el disector NFS podría bloquearse. Esto se abordó en el archivo epan/dissectors/packet-nfs.c impidiendo la recurrencia excesiva, como por ejemplo, un ciclo en el gráfico de directorio en un sistema de archivos. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00038.html https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=16476 https://code.wireshark.org/review/gitweb?p=wireshark.git%3Ba=commit%3Bh=e6e98eab8e5e0bbc982cfdc808f2469d7cab6c5a https://lists.debian.org/debian-lts-announce/2021/02/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5UOISPQTRCZGQLKBVXEDL72AEXEHS425 https://lists • CWE-674: Uncontrolled Recursion •

A memory corruption issue was found in DPDK versions 17.05 and above. This flaw is caused by an integer truncation on the index of a payload. Under certain circumstances, the index (a UInt) is copied and truncated into a uint16, which can lead to out of bound indexing and possible memory corruption. Se encontró un problema de corrupción de memoria en DPDK versiones 17.05 y superiores. Este fallo es causado por un truncamiento de enteros en el índice de una carga útil. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00045.html https://bugs.dpdk.org/show_bug.cgi?id=268 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10723 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HRHKFVV4MRWNNJOYQOVP64L4UVWYPEO4 https://usn.ubuntu.com/4362-1 https://www.openwall.com/lists/oss-security/2020/05/18/2 https://www.oracle.com/security-alerts/cpujan2021.html https://www.oracle.com/security-alerts/cpuoct2020&# • CWE-190: Integer Overflow or Wraparound •

PowerDNS Recursor from 4.1.0 up to and including 4.3.0 does not sufficiently defend against amplification attacks. An issue in the DNS protocol has been found that allow malicious parties to use recursive DNS services to attack third party authoritative name servers. The attack uses a crafted reply by an authoritative name server to amplify the resulting traffic between the recursive and other authoritative name servers. Both types of service can suffer degraded performance as an effect. This is triggered by random subdomains in the NSDNAME in NS records. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00052.html http://www.nxnsattack.com https://doc.powerdns.com/recursor/security-advisories/powerdns-advisory-2020-01.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NMP72NJGKBWR5WEBXAWX5KSLQUDFTG6S https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PS4ZN5XGENYNFKX7QIIOUCQQHXE37GJF https://www.debian.org/security/2020/dsa-4691 • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2020-10135
Legacy pairing and secure-connections pairing authentication in Bluetooth BR/EDR Core Specification v5.2 and earlier may allow an unauthenticated user to complete authentication without pairing credentials via adjacent access. An unauthenticated, adjacent attacker could impersonate a Bluetooth BR/EDR master or slave to pair with a previously paired remote device to successfully complete the authentication procedure without knowing the link key. El emparejamiento heredado y la identificación de emparejamiento de conexiones seguras en Bluetooth BR / EDR Core Specification v5.2 y anteriores pueden permitir que un usuario no identificado complete la autenticación sin emparejar credenciales a través de acceso adyacente. Un atacante adyacente no autenticado podría hacerse pasar por un maestro o esclavo Bluetooth BR / EDR para emparejarse con un dispositivo remoto previamente emparejado para completar con éxito el procedimiento de autenticación sin conocer la clave de enlace A flaw was discovered in the Bluetooth protocol affecting the Bluetooth BR/EDR authentication. An attacker with physical access to the Bluetooth connection could perform a spoofing attack impersonating the address of a previously paired remote device. • https://github.com/m4rm0k/CVE-2020-10135-BIAS http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00047.html http://packetstormsecurity.com/files/157922/Bluetooth-Impersonation-Attack-BIAS-Proof-Of-Concept.html http://seclists.org/fulldisclosure/2020/Jun/5 https://francozappa.github.io/about-bias https://kb.cert.org/vuls/id/647177 https://www.bluetooth.com/learn-about-bluetooth/bluetooth-technology/bluetooth-securit • CWE-290: Authentication Bypass by Spoofing CWE-757: Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade') •
