From Exploited flaws, HARD’s guide to the flaws being used in attacks · Checked
This article is about a flaw in Digiever DS-2105 Pro. For every flaw being used in attacks, see Exploited flaws.

CVE-2023-52163 is a security flaw in Digiever DS-2105 Pro. Attackers can run commands on Digiever DS-2105 Pro. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 22 Dec 2025.[1]

Digiever DS-2105 Pro is business software or equipment. Most families won’t have it, but attackers break into it to get inside companies, and from there to what those companies hold about their customers, patients and staff. Digiever has published a fix or advice.

Description

CISA calls it a missing authorization in Digiever DS-2105 Pro. In its words: “Digiever DS-2105 Pro contains a missing authorization vulnerability which could allow for command injection via time_tzsetup.cgi.”[1]

The CVE record adds: “Digiever DS-2105 Pro 3.1.0.71-11 devices allow time_tzsetup.cgi Command Injection. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.”[2]

The underlying weakness is missing authorization (CWE-862), in MITRE’s list of common software weaknesses.

It scores 8.8 out of 10 on the Common Vulnerability Scoring System, which rates it high, scored by the organisation that published the CVE using CVSS 3.1.[2]

Affected versions

NVD’s record doesn’t list version ranges for it; Digiever’s advisory has them[3]. CISA names the product as Digiever DS-2105 Pro.

Most families won’t have Digiever DS-2105 Pro; it’s for whoever looks after IT at work.

Exploitation

CISA added it to its catalog of known exploited vulnerabilities on 22 Dec 2025, 322 days after it was made public. CISA lists a flaw only when it has reliable evidence of it being exploited, and gave US federal agencies until 12 Jan 2026 to fix it.[1]

FIRST’s Exploit Prediction Scoring System, which estimates how likely a flaw is to be used in attacks in the next 30 days from what it sees across the internet, puts it at 97%. That’s in the top 1% of the flaws it scores.[4]

CISA assesses it as not automatable: each attack takes some work.

CISA doesn’t say who was attacked, or how.

Fix

Digiever has published a fix or advice.[3] CISA’s required action: “Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.”[1]

  1. Check whether you use it.Digiever DS-2105 Pro is business software or equipment, so most families won’t have it. If you run a business, or work from home on company equipment, ask whoever looks after your IT.
  2. Send this page to your IT person.Ask them to confirm it’s fixed, or not in use. CISA gave US government agencies until 12 Jan 2026 to fix it.
  3. If it can’t be fixed, take it offline.CISA’s advice when there’s no fix is to stop using the product, or take it off the internet, until there is one.

You can’t fix someone else’s server, but you can watch for what follows a break-in like this: a breach notice, a password reset you didn’t ask for, or a scam message that knows things it shouldn’t. HARD watches for those for you and your family.
