CVE-2024-8957

From Exploited flaws, HARD’s guide to the flaws being used in attacks · Checked
This article is about a flaw in PTZOptics PT30X-SDI/NDI Cameras. For every flaw being used in attacks, see Exploited flaws.

CVE-2024-8957 is a security flaw in PTZOptics PT30X-SDI/NDI Cameras. Attackers can run commands on PTZOptics PT30X-SDI/NDI Cameras from anywhere, without logging in. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 4 Nov 2024.[1]

PTZOptics PT30X-SDI/NDI Cameras 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. Fixed in version 6.3.40.

Description

CISA calls it an OS command injection in PTZOptics PT30X-SDI/NDI Cameras. In its words: “PTZOptics PT30X-SDI/NDI cameras contain an OS command injection vulnerability that allows a remote, authenticated attacker to escalate privileges to root via a crafted payload with the ntp_addr parameter of the /cgi-bin/param.cgi CGI script.”[1]

The CVE record adds: “PTZOptics PT30X-SDI/NDI-xx before firmware 6.3.40 is vulnerable to an OS command injection issue. The camera does not sufficiently validate the ntp_addr configuration value which may lead to arbitrary command execution when ntp_client is started. When chained with CVE-2024-8956, a remote and unauthenticated attacker can execute arbitrary OS commands on affected devices.”[2]

The underlying weakness is OS command injection (CWE-78), in MITRE’s list of common software weaknesses.

It scores 7.2 out of 10 on the Common Vulnerability Scoring System, which rates it high, scored by NVD using CVSS 3.1.[2]

Most families won’t have PTZOptics PT30X-SDI/NDI Cameras; it’s for whoever looks after IT at work.

Exploitation

CISA added it to its catalog of known exploited vulnerabilities on 4 Nov 2024, 48 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 25 Nov 2024 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 80%. 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

PTZOptics has published a fix or advice.[3] CISA’s required action: “Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.”[1]

  1. Check whether you use it.PTZOptics PT30X-SDI/NDI Cameras 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 (fixed in version 6.3.40), or not in use. CISA gave US government agencies until 25 Nov 2024 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.
