Net::CIDR::Set versions through 0.20 for Perl did not validate network masks. The mask portion of a network mask could contain Unicode digits such as the Arabic-Indic One (U+0661), or non-digits, which were ignored. This could allow network masks to accept larger networks. Leading zeros were also accepted, but treated as decimal instead of octal. This could lead to confusion about what networ…

An issue was discovered in OpenStack oslo.messaging 1.0.0 through 17.3.0. The oslo.messaging RabbitMQ driver does not perform TLS hostname verification when connecting to the message broker. When ssl_ca_file is configured, the driver enables certificate chain validation but does not pass the expected broker hostname into the underlying TLS stack. Any certificate signed by the deployment CA is acce…

High-risk TrustAllCerts routines disable standard TLS certificate validation. Combined with hard-coded DES symmetric encryption keys, a Man-in-the-Middle (MITM) actor could decrypt network traffic.

In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix WQ_MEM_RECLAIM warning When sunrpc is used, if a reset triggered, our wq may lead the following trace: workqueue: WQ_MEM_RECLAIM xprtiod:xprt_rdma_connect_worker [rpcrdma] is flushing !WQ_MEM_RECLAIM hns_roce_irq_workq:flush_work_handle [hns_roce_hw_v2] WARNING: CPU: 0 PID: 8250 at kernel/workqueue.c:2644 check_fl…

OP-TEE is a Trusted Execution Environment (TEE) designed as companion to a non-secure Linux kernel running on Arm; Cortex-A cores using the TrustZone technology. Starting in version 3.16.0 and prior to 4.11.0, a user-after-free (UAF) race condition exists in the shared memory teardown logic of FF-A within OP-TEE SPMC/SP flows. This only applies when OP-TEE is configured as an SPMC for S-EL0 SPs, …

Files or directories accessible to external parties vulnerability in ABB T-MAC Plus. This issue affects T-MAC Plus: 4.0-24.

El módulo email de Python versiones 3.11.3 y anteriores contiene un fallo en la función _parseaddr.py que permite a atacantes eludir mecanismos de autenticación basados en validación de dominio de correo electrónico. Un atacante puede fabricar direcciones de correo con caracteres especiales que el parser interpreta incorrectamente, permitiendo registros no autorizados en aplicaciones que restringen el acceso solo a direcciones de dominios específicos (como @empresa.com). Esto afecta directamente servicios web y plataformas SaaS en México y LATAM que utilizan Python para procesar correos.

Dräger Infinity Acute Care System and Standalone Infinity M540 patient monitors versions VG4.1.1, VG4.0.3, and lower (with VG4.2 partially affected) contain a network message handling vulnerability that allows remote attackers to inject spoofed or tampered data and cause denial-of-service conditions. Attackers can compromise network communications to modify device settings such as alarm states or …

authentik is an open-source identity provider. Prior to versions 2025.12.5, 2026.2.3, and 2026.5.1, authentik's SAML Source ACS endpoint is vulnerable to XML Signature Wrapping when validating upstream SAML responses. An attacker with any account at the upstream IdP can reuse a valid signed assertion to authenticate as another federated user. This issue has been patched in versions 2025.12.5, 2026…

authentik is an open-source identity provider. Prior to versions 2025.12.5 and 2026.2.3, the SAML source response processor (ResponseProcessor.parse()) does not validate the Conditions element on assertions. NotBefore, NotOnOrAfter, and AudienceRestriction are all ignored. This allows replay of expired assertions and acceptance of assertions intended for other service providers. This issue has bee…

React Router is a router for React. In versions 7.0.0 through 7.14.x of react-router and versions 2.10.0 through 2.17.4 of @remix-run/server-runtime, certain crafted requests can consume disproportionate server resources via unbounded path expansion in the __manifest endpoint, resulting in response time degradation and/or service unavailability for end users. This affects React Router Framework Mo…

NiceGUI is a Python-based UI framework. Prior to version 3.12.0, ui.restructured_text() renders reStructuredText server-side with Docutils without disabling file insertion directives. When a NiceGUI application passes attacker-controlled content to ui.restructured_text(), an attacker can use standard Docutils directives (include, csv-table with :file:, raw with :file:) to read local files readable…

CWE-639: Authorization Bypass Through User-Controlled Key in web services in Progress Sitefinity 15.2.x before 15.2.8441, 15.3.x before 15.3.8531, and 15.4.x before 15.4.8630 allows a remote authenticated attacker to modify account properties of other users, potentially leading to account compromise. Successful exploitation requires knowledge of values that are not generally exposed to low-privile…

A path traversal vulnerability exists in jupyter-server version 2.17.0 due to an incorrect root directory boundary check in the _get_os_path() function within jupyter_server/services/contents/fileio.py. The check uses startswith(root) without appending a trailing path separator, allowing sibling directories with names starting with the same prefix as root_dir to bypass the check. Additionally, the…

OpenSSL contiene un defecto en la operación de squaring Montgomery en arquitectura x86_64 que afecta procesadores con extensiones BMI1, BMI2 y ADX (Intel Broadwell 5ª gen en adelante, AMD Ryzen). Los ataques contra RSA y DSA son muy difíciles de ejecutar. Los ataques contra Diffie-Hellman son factibles pero requieren acceso online a sistemas sin parchar y claves privadas compartidas entre múltiples clientes, lo que limita el riesgo en la mayoría de entornos empresariales en LATAM.

Se ha identificado una vulnerabilidad de elevación de privilegios en el controlador Ancillary Function Driver for WinSock de Windows que permite a atacantes locales ejecutar código con permisos del sistema. Esta vulnerabilidad afecta servidores y estaciones de trabajo en entornos empresariales de LATAM donde usuarios con acceso local pueden comprometer la seguridad del sistema operativo. El riesgo es significativo en infraestructuras compartidas, centros de datos y terminales de usuario final.

Vulnerabilidad de lectura fuera de límites (out-of-bounds read) en la función smb2_compound_op() del cliente SMB de Windows. Puede ser explotada remotamente por atacantes en la red para leer información sensible de memoria o causar denegación de servicio. Afecta servidores y estaciones de trabajo en entornos corporativos que utilizan SMB2 para compartir archivos y servicios.

CVE-2023-6606 es una vulnerabilidad de lectura fuera de límites (out-of-bounds read) en la función SMBCalcSize del kernel de Windows, que puede ser explotada por atacantes con acceso a la red para obtener información sensible del sistema. En entornos empresariales de LATAM, esta vulnerabilidad afecta particularmente a servidores que implementan comparticiones SMB/CIFS, exponiendo datos de memoria del kernel a atacantes no autenticados. El riesgo es moderado pero requiere atención inmediata en infraestructuras de archivo y autenticación.

Palo Alto Networks ha publicado una alerta de seguridad sobre una vulnerabilidad de tipo SSRF (Server-Side Request Forgery) en la funcionalidad de descarga de certificados IKEv2 de PAN-OS. Esta vulnerabilidad podría permitir a atacantes acceder a recursos internos o realizar solicitudes no autorizadas desde los firewalls afectados. Impacta directamente a empresas mexicanas y latinoamericanas que dependen de Palo Alto Networks para su infraestructura de seguridad perimetral y VPN.
