Descriptions

1E Client installer can perform arbitrary file deletion on protected files.  

A non-privileged user could provide a symbolic link or Windows junction to point to a protected directory in the installer that the 1E Client would then clear on service startup.

A hotfix is available from the 1E support portal that forces the 1E Client to check for a symbolic link or junction and if it finds one refuses to use that path and instead creates a path involving a random GUID.

for v8.1 use hotfix Q23097
for v8.4 use hotfix Q23105
for v9.0 use hotfix Q23115

for SaaS customers, use 1EClient v23.7 plus hotfix Q23121

El instalador de 1E Client puede realizar la eliminación arbitraria de archivos protegidos. Un usuario sin privilegios podría proporcionar un enlace simbólico o una unión de Windows para apuntar a un directorio protegido en el instalador que el Cliente 1E borraría al iniciar el servicio. Hay una revisión disponible en el portal de soporte 1E que obliga al Cliente 1E a buscar un enlace o cruce simbólico y, si encuentra uno, se niega a usar esa ruta y en su lugar crea una ruta que involucra un GUID aleatorio para v8.1 use hotfix Q23097 para v8.4 use hotfix Q23105 para v9.0 use hotfix Q23115 para clientes de SaaS, use 1EClient v23.7 plus hotfix Q23121
