Vulnerability from certfr_avis - Published: 2009-08-18 - Updated: 2009-08-18
Plusieurs vulnérabilités dans IBM WebSphere Application Server ont été publiées. Certaines permettent à un utilisateur malveillant d'exécuter du code arbitraire à distance.
Description
Plusieurs vulnérabilités dans IBM WebSphere Application Server ont été publiées :
- le composant Security présente un défaut qui permet à un utilisateur malveillant de contourner à distance les restrictions d'accès ;
- un problème dans le composant Web Service permet à un utilisateur local de réaliser un déni de service ;
- dans certaines configurations, lors de l'utilisation de SPNEGO Single Sign-On, un utilisateur malveillant distant peut contourner l'authentification ;
- le composant de migration permet à un utilisateur authentifié distant d'obtenir indûment des informations sensibles ;
- un défaut non précisé du composant System Management/Repository permet à un utilisateur malveillant distant de contourner les restrictions d'accès et d'arrêter un service ;
- sur un système z/OS, le composant System Management/Repository utilise des droits d'accès permissifs, permettant à un utilisateur malveillant d'obtenir des données sensibles ;
- une lecture erronée du paramètre portletServingEnabled permet à un utilisateur malveillant distant de contourner les restrictions d'accès.
Solution
Les versions 7.0.0.5 et 6.1.0.25 corrigent ces vulnérabilités.

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
