CVSS: 5.5EPSS: 0%CPEs: 18EXPL: 1CVE-2020-15358 – sqlite: heap-based buffer overflow in multiSelectOrderBy due to mishandling of query-flattener optimization in select.c
https://notcve.org/view.php?id=CVE-2020-15358
In SQLite before 3.32.3, select.c mishandles query-flattener optimization, leading to a multiSelectOrderBy heap overflow because of misuse of transitive properties for constant propagation. En SQLite versiones anteriores a 3.32.3, el archivo select.c maneja inapropiadamente la optimización query-flattener, conllevando a un desbordamiento de la pila de multiSelectOrderBy debido al uso inapropiado de las propiedades transitivas para la propagación constante A heap buffer overflow was found in SQLite in the query flattening optimization technique. This flaw allows an attacker to execute SQL statements to crash the application, resulting in a denial of service. • http://seclists.org/fulldisclosure/2020/Dec/32 http://seclists.org/fulldisclosure/2020/Nov/19 http://seclists.org/fulldisclosure/2020/Nov/20 http://seclists.org/fulldisclosure/2020/Nov/22 http://seclists.org/fulldisclosure/2021/Feb/14 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://security.gentoo.org/glsa/202007-26 https://security.netapp.com/advisory/ntap-20200709-0001 https://support.apple.com/kb/HT211843 https://support.apple.com/kb/HT211844 https • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 23EXPL: 0CVE-2020-11080 – Denial of service in nghttp2
https://notcve.org/view.php?id=CVE-2020-11080
In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of settings entries are large (e.g., > 32), then drop the connection. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00024.html https://github.com/nghttp2/nghttp2/commit/336a98feb0d56b9ac54e12736b18785c27f75090 https://github.com/nghttp2/nghttp2/commit/f8da73bd042f810f34d19f9eae02b46d870af394 https://github.com/nghttp2/nghttp2/security/advisories/GHSA-q5wr-xfw9-q7xr https://lists.debian.org/debian-lts-announce/2021/10/msg00011.html https://lists.debian.org/debian-lts-announce/2023/10/msg00023.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject& • CWE-400: Uncontrolled Resource Consumption CWE-707: Improper Neutralization CWE-770: Allocation of Resources Without Limits or Throttling •
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 •
