Vulnerability from certfr_alerte - Published: 2005-10-07 - Updated: 2013-06-06
Une vulnérabilité dans certains produits Citrix permet à un utilisateur mal intentionné de contourner la politique de sécurité.
Description
Une vulnérabilité découverte dans la politique de filtrage basée sur la variable client name permet à un utilisateur distant mal intentionné de contourner la politique de sécurité. Une personne malveillante peut s'authentifier auprès du serveur après avoir habilement modifié le fichier launch.ica.
Contournement provisoire
Changer la politique de sécurité de l'application Citrix de manière à ce que l'authentification ne se fasse pas par le biais de la variable client name.
Solution
Ce produit n'est plus maintenu par l'éditeur. Il convient de migrer vers une version soutenue du produit. Se référer au bulletin de sécurité de l'éditeur pour plus d'informations (cf. section Documentation).

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.
