CVE-2024-20953
CVE-2024-20953 is a security flaw in Oracle Agile Product Lifecycle Management (PLM). Attackers are using a flaw in Oracle Agile Product Lifecycle Management (PLM). The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 24 Feb 2025.[1]
Oracle Agile Product Lifecycle Management (PLM) 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. Oracle has published a fix or advice.
Description
CISA calls it a deserialization in Oracle Agile Product Lifecycle Management (PLM). In its words: “Oracle Agile Product Lifecycle Management (PLM) contains a deserialization vulnerability that allows a low-privileged attacker with network access via HTTP to compromise the system.”[1]
The CVE record adds: “Vulnerability in the Oracle Agile PLM product of Oracle Supply Chain (component: Export). The supported version that is affected is 9.3.6. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Agile PLM. Successful attacks of this vulnerability can result in takeover of Oracle Agile PLM. CVSS 3.1 Base Score 8.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).”[2]
The underlying weakness is deserialization of untrusted data (CWE-502), 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; Oracle’s advisory has them[3]. CISA names the product as Oracle Agile Product Lifecycle Management (PLM).
Most families won’t have Oracle Agile Product Lifecycle Management (PLM); it’s for whoever looks after IT at work.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 24 Feb 2025, 373 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 17 Mar 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 4%. That’s in the top 10% 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
Oracle 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.Oracle Agile Product Lifecycle Management (PLM) 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, or not in use. CISA gave US government agencies until 17 Mar 2025 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.
