FKIE_CVE-2025-24783

Vulnerability from fkie_nvd - Published: 2025-01-27 15:15 - Updated: 2025-07-15 16:27
Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Summary
** UNSUPPORTED WHEN ASSIGNED ** Incorrect Usage of Seeds in Pseudo-Random Number Generator (PRNG) vulnerability in Apache Cocoon. This issue affects Apache Cocoon: all versions. When a continuation is created, it gets a random identifier. Because the random number generator used to generate these identifiers was seeded with the startup time, it may not have been sufficiently unpredictable, and an attacker could use this to guess continuation ids and look up continuations they should not have had access to. As a mitigation, you may enable the "session-bound-continuations" option to make sure continuations are not shared across sessions. As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

      "value": "** NO SOPORTADO CUANDO SE ASIGN\u00d3 ** Vulnerabilidad de uso incorrecto de las semillas en el generador de n\u00fameros pseudoaleatorios (PRNG) en Apache Cocoon. Este problema afecta a Apache Cocoon: todas las versiones. Cuando se crea una continuaci\u00f3n, obtiene un identificador aleatorio. Debido a que el generador de n\u00fameros aleatorios utilizado para generar estos identificadores se sembr\u00f3 con la hora de inicio, es posible que no haya sido lo suficientemente impredecible y un atacante podr\u00eda usar esto para adivinar los identificadores de continuaci\u00f3n y buscar continuaciones a las que no deber\u00eda haber tenido acceso. Como mitigaci\u00f3n, puede habilitar la opci\u00f3n \"continuaciones vinculadas a la sesi\u00f3n\" para asegurarse de que las continuaciones no se compartan entre sesiones. Como este proyecto est\u00e1 retirado, no planeamos lanzar una versi\u00f3n que solucione este problema. Se recomienda a los usuarios que busquen una alternativa o restrinjan el acceso a la instancia a usuarios de confianza. NOTA: Esta vulnerabilidad solo afecta a los productos que ya no reciben soporte del fabricante."
