CVE-2024-8956
CVE-2024-8956 is a security flaw in PTZOptics PT30X-SDI/NDI Cameras. Attackers can run their own code 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 authentication bypass in PTZOptics PT30X-SDI/NDI Cameras. In its words: “PTZOptics PT30X-SDI/NDI cameras contain an insecure direct object reference (IDOR) vulnerability that allows a remote, attacker to bypass authentication for the /cgi-bin/param.cgi CGI script. If combined with CVE-2024-8957, this can lead to remote code execution as root.”[1]
The CVE record adds: “PTZOptics PT30X-SDI/NDI-xx before firmware 6.3.40 is vulnerable to an insufficient authentication issue. The camera does not properly enforce authentication to /cgi-bin/param.cgi when requests are sent without an HTTP Authorization header. The result is a remote and unauthenticated attacker can leak sensitive data such as usernames, password hashes, and configurations details. Additionally, the attacker can update individual configuration values or overwrite the whole file.”[2]
The underlying weakness is improper authentication (CWE-287), in MITRE’s list of common software weaknesses.
It scores 9.1 out of 10 on the Common Vulnerability Scoring System, which rates it critical, scored by NVD using CVSS 3.1.[2]
Affected versions
NVD’s record lists these fixed versions: in each line, everything before the version shown is affected.[2]
| Product | Fixed in |
|---|---|
| PT30X-SDI | 6.3.40 |
| PT30X-NDI | 6.3.40 |
| pt30x-sdi_firmware | 6.3.40 |
| pt30x-ndi-xx-g2_firmware | 6.3.40 |
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 59%. That’s in the top 1% of the flaws it scores.[4]
CISA assesses it as automatable: attackers can run it against many targets at once.
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]
- 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.
- 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.
- 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.
