Vulnerabilidades

Con el objetivo de informar, advertir y ayudar a los profesionales sobre las últimas vulnerabilidades de seguridad en sistemas tecnológicos, ponemos a disposición de los usuarios interesados en esta información una base de datos con información en castellano sobre cada una de las últimas vulnerabilidades documentadas y conocidas.

Este repositorio con más de 75.000 registros esta basado en la información de NVD (National Vulnerability Database) – en función de un acuerdo de colaboración – por el cual desde INCIBE realizamos la traducción al castellano de la información incluida. En ocasiones este listado mostrará vulnerabilidades que aún no han sido traducidas debido a que se recogen en el transcurso del tiempo en el que el equipo de INCIBE realiza el proceso de traducción.

Se emplea el estándar de nomenclatura de vulnerabilidades CVE (Common Vulnerabilities and Exposures), con el fin de facilitar el intercambio de información entre diferentes bases de datos y herramientas. Cada una de las vulnerabilidades recogidas enlaza a diversas fuentes de información así como a parches disponibles o soluciones aportadas por los fabricantes y desarrolladores. Es posible realizar búsquedas avanzadas teniendo la opción de seleccionar diferentes criterios como el tipo de vulnerabilidad, fabricante, tipo de impacto entre otros, con el fin de acortar los resultados.

Mediante suscripción RSS o Boletines podemos estar informados diariamente de las últimas vulnerabilidades incorporadas al repositorio.

*** Pendiente de traducción *** libde265 is an open source implementation of the h.265 video codec. Versions prior to 1.0.19 have a heap buffer overflow (out-of-bounds READ) exists in `decoder_context::decode_slice_unit_WPP()` in `libde265/decctx.cc`. When decoding a WPP (Wavefront Parallel Processing) HEVC slice, `ctbAddrRS` is computed as `ctbRow * ctbsWidth` inside the entry-point loop. If the PPS/SPS headers are crafted so that this value exceeds `pps.CtbAddrRStoTS.size()`, the subsequent array access `pps.CtbAddrRStoTS[ctbAddrRS]` reads past the end of the allocated vector, triggering a heap-buffer-overflow confirmed by AddressSanitizer. Version 1.0.19 patches the issue.

*** Pendiente de traducción *** Kubeflow Community Distribution helps users to install Kubeflow Platform in popular Kubernetes clusters. Prior to version 26.03-rc.1, a Kubeflow setup based on the official manifests or most other packaged Kubeflow distributions is vulnerable to authorization token stealing from any user of the Kubeflow UI or APIs, such as the Dashboard, Pipelines API, or Notebooks. With this token, the attacker can take over the user's account and the data that is processed by that user. The attacker needs a valid user with the ``kubeflow-edit`` role / Contributor role in a random Kubeflow namespace to perform this attack. This is given if _Automatic Profile Creation_ is enabled. Version 26.03-rc.1 fixes the issue.

*** Pendiente de traducción *** FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to versions 1.5.10.1832 and 1.6.0-beta.2313, the `selectForm()` helper in `fogpage.class.php` renders `` labels using raw, unescaped user input. An unauthenticated attacker who knows any registered host's MAC address can POST a malicious `sysproduct` value to `/service/inventory.php`, which is stored in the database. When an administrator opens Reports > Inventory, the payload breaks out of the `` element and executes arbitrary JavaScript in the admin's browser. Versions 1.5.10.1832 and 1.6.0-beta.2313 fix the issue.

*** Pendiente de traducción *** FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to versions 1.5.10.1832 and 1.6.0-beta.2313, the `clearAES` and `clearPMTasks` methods in `FOGPage` can be invoked by an unauthenticated attacker via a single HTTP GET request through the public `client` node endpoint. This allows remote wiping of host AES encryption credentials and deletion of all power management scheduled tasks, with no login, session, or CSRF token required. Versions 1.5.10.1832 and 1.6.0-beta.2313 fix the issue.

*** Pendiente de traducción *** FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to versions 1.5.10.1832 and 1.6.0-beta.2313, the `buildRow()` method in `fogpage.class.php` substitutes data values into HTML table cell templates using `str_replace()` without any HTML escaping. An unauthenticated attacker who knows any registered host's MAC address can POST malicious inventory values (e.g. `sysproduct`, `sysserial`) to `/service/inventory.php`, which stores them in the database. When an administrator opens the Group Inventory tab, the payload renders as executable HTML/JavaScript in the admin's browser. Versions 1.5.10.1832 and 1.6.0-beta.2313 fix the issue.

*** Pendiente de traducción *** Capstone is a disassembly framework. Versions prior to 6.0.0-Alpha8 and 5.0.8 have a NULL pointer dereference in `modRMRequired()` and `decode()` when disassembling 3DNow! opcodes (`0F 0F`) in builds compiled with `-DCAPSTONE_X86_REDUCE`, allowing a remote attacker to crash any application using the reduced X86 Capstone library by supplying a crafted input containing the 4-byte sequence `0F 0F `. Versions 6.0.0-Alpha8 and 5.0.8 patch the issue.

*** Pendiente de traducción *** FlaskBB is a Forum Software written in Python using the micro framework Flask. Prior to version 2.2.1, a Server-Side Request Forgery (SSRF) vulnerability in get_image_info() allows any authenticated user to force the server to send HTTP requests to arbitrary internal endpoints, including cloud metadata services. This is a blind SSRF with confirmed internal port scanning and internal API triggering capabilities. Version 2.2.1 patches the issue.

*** Pendiente de traducción *** FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to versions 1.5.10.1832 and 1.6.0-beta.2313, the unauthenticated inventory service endpoint (`/service/inventory.php`) persists client-supplied values without sanitization, and the Host Management Inventory page renders all static inventory fields into HTML without output encoding, allowing stored cross-site scripting that executes in any administrator's browser. Versions 1.5.10.1832 and 1.6.0-beta.2313 fix the issue.

CVE-2026-16317

Fecha de publicación:

Idioma:

*** Pendiente de traducción *** Missing validation of the outer content_type byte on TLS 1.3 encrypted records in s2n-tls allows an active man-in-the-middle to silently discard individual application data records without either endpoint detecting the modification. RFC 8446 Section 5.2 requires that the outer content_type of all encrypted TLS 1.3 records must be application_data (0x17). The s2n-tls AEAD implementation hardcodes this value in the additional authenticated data rather than using the actual wire byte, so the outer content_type is not covered by the authentication tag. <br /> <br /> <br /> <br /> This enables selective suppression of application data. In HTTP pipelining scenarios, dropping a TLS record containing an HTTP request can cause request/response desynchronization, where subsequent responses are delivered to the wrong requests. In write-heavy workloads, a dropped record containing a write request can result in undetectable data loss when the client interprets a subsequent success response as confirmation of the dropped write.<br /> <br /> <br /> <br /> All TLS 1.3 connections are affected. Both TLS clients and servers are affected. TLS 1.2 and QUIC connections are not affected.<br /> <br /> <br /> <br /> We recommend you upgrade s2n-tls to version v1.7.6

CVE-2026-16318

*** Pendiente de traducción *** The QUIC transport parameters extension handler in s2n-tls incorrectly uses s2n_alloc instead of s2n_realloc to store the peer&amp;#39;s transport parameters. When a TLS 1.3 connection goes through a HelloRetryRequest, the handler is called twice on the same connection. On the second call, s2n_alloc zeroes the existing pointer before allocating new memory, causing the first allocation to be leaked.<br /> <br /> <br /> <br /> This can occur during normal QUIC traffic when a client offers a key share group the server does not prefer. An unauthenticated user can amplify the issue by deliberately forcing HelloRetryRequests, causing up to approximately 64 KB of unreachable memory per handshake. Over time, this can lead to increased memory consumption on long-running server processes. The unreachable memory is only reclaimed when the process is restarted.<br /> <br /> <br /> <br /> Only server-side QUIC-enabled deployments are affected. Non-QUIC TLS connections are not affected.<br /> <br /> <br /> <br /> We recommend you upgrade s2n-tls to version v1.7.6
