CVE-2025-48703

From Exploited flaws, HARD’s guide to the flaws being used in attacks · Checked
This article is about a flaw in CWP Control Web Panel. For every flaw being used in attacks, see Exploited flaws.

CVE-2025-48703 is a security flaw in CWP Control Web Panel. Attackers can run their own code on CWP Control Web Panel 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 2025.[1]

CWP Control Web Panel 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 0.9.8.1205 of CentOS Web Panel.

Description

CISA calls it an OS command injection in CWP Control Web Panel. In its words: “CWP Control Web Panel (formerly CentOS Web Panel) contains an OS command Injection vulnerability that allows unauthenticated remote code execution via shell metacharacters in the t_total parameter in a filemanager changePerm request. A valid non-root username must be known.”[1]

The underlying weakness is OS command injection (CWE-78), in MITRE’s list of common software weaknesses.[2]

It scores 9.0 out of 10 on the Common Vulnerability Scoring System, which rates it critical, scored by the organisation that published the CVE using CVSS 3.1.[2]

Affected versions

NVD’s record lists one fixed version: everything before it is affected.[2]

Most families won’t have CWP Control Web Panel; it’s for whoever looks after IT at work.

Exploitation

CISA added it to its catalog of known exploited vulnerabilities on 4 Nov 2025, 46 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 2025 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 over 99%. 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

CWP 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.CWP Control Web Panel 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 0.9.8.1205 of CentOS Web Panel), or not in use. CISA gave US government agencies until 25 Nov 2025 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.
