From Exploited flaws, HARD’s guide to the flaws being used in attacks · Checked
This article is about a flaw in Kingsoft WPS Office. For every flaw being used in attacks, see Exploited flaws.

CVE-2024-7262 is a security flaw in Kingsoft WPS Office. Attackers can read files on Kingsoft WPS Office that should be out of reach. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 3 Sep 2024.[1]

Kingsoft WPS Office 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 12.2.0.16412 and 12.2.0.13489.

Description

CISA calls it a path traversal in Kingsoft WPS Office. In its words: “Kingsoft WPS Office contains a path traversal vulnerability in promecefpluginhost.exe on Windows that allows an attacker to load an arbitrary Windows library.”[1]

The CVE record adds: “Improper path validation in promecefpluginhost.exe in Kingsoft WPS Office version ranging from 12.2.0.13110 to 12.2.0.16412 (exclusive) on Windows allows an attacker to load an arbitrary Windows library. The vulnerability was found weaponized as a single-click exploit in the form of a deceptive spreadsheet document”[2]

The underlying weakness is path traversal (CWE-22), in MITRE’s list of common software weaknesses.

It scores 7.8 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 Kingsoft WPS Office; it’s for whoever looks after IT at work.

Exploitation

CISA added it to its catalog of known exploited vulnerabilities on 3 Sep 2024, 19 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 24 Sep 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 3%. That’s in the top 13% 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

Kingsoft 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.Kingsoft WPS Office 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 12.2.0.16412 and 12.2.0.13489), or not in use. CISA gave US government agencies until 24 Sep 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.
