Vulnerability from variot - Updated: 2023-12-18 12:44

Synology Made of multiple NAS The server has authentication information common to all devices. Certificate and password management (CWE-255) - CVE-2016-6554 Synology Made of NAS server Is DS107 , DS116 and DS213 By default, the authentication information "guest:( No password )" and "admin:( No password )" Is set.A remote third party could access the device with administrator privileges. Multiple Synology DiskStation products are prone to an insecure default-password vulnerability. Remote attackers with knowledge of the default credentials may exploit this vulnerability to gain unauthorized access and perform unauthorized actions. This may aid in further attacks. The following products are affected: Synology DiskStation DS107 running firmware versions 3.1-1639 and prior. Synology DiskStation DS116 running firmware versions prior to 5.2-5644-1. Synology DiskStation DS213 running firmware versions prior to 5.2-5644-1. Synology DiskStation DS107 and others are network storage servers (NAS) of Synology. A trust management vulnerability exists in several Synology products due to the use of non-random default credentials (guest: (blank) and admin: (blank))

Multiple Synology DiskStation products are prone to an insecure default-password vulnerability. \nRemote attackers with knowledge of the default credentials may exploit this vulnerability to gain unauthorized access and perform unauthorized actions. This may aid in further attacks. \nThe following products are affected:\nSynology DiskStation DS107 running firmware versions 3.1-1639 and prior. \nSynology DiskStation DS116 running firmware versions prior to 5.2-5644-1. \nSynology DiskStation DS213 running firmware versions prior to 5.2-5644-1. Synology DiskStation DS107 and others are network storage servers (NAS) of Synology. A trust management vulnerability exists in several Synology products due to the use of non-random default credentials (guest: (blank) and admin: (blank))",

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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
