CVE-2023-35081
CVE-2023-35081 is a security flaw in Ivanti Endpoint Manager Mobile (EPMM), software companies use to manage staff phones. Attackers can get into Ivanti Endpoint Manager Mobile (EPMM) without a valid password. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 31 Jul 2023.[1]
Ivanti Endpoint Manager Mobile (EPMM) 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 11.10.0.3 of EPMM.
Description
CISA calls it a path traversal in Ivanti Endpoint Manager Mobile (EPMM). In its words: “Ivanti Endpoint Manager Mobile (EPMM) contains a path traversal vulnerability that enables an authenticated administrator to perform malicious file writes to the EPMM server. This vulnerability can be used in conjunction with CVE-2023-35078 to bypass authentication and ACLs restrictions (if applicable).”[1]
The underlying weakness is path traversal (CWE-22), in MITRE’s list of common software weaknesses.[2]
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]

NVD’s record lists one fixed version: everything before it is affected.[2]
| Product | Fixed in |
|---|---|
| EPMM | 11.10.0.3 |
Most families won’t have Ivanti Endpoint Manager Mobile (EPMM); it’s for whoever looks after IT at work.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 31 Jul 2023. CISA lists a flaw only when it has reliable evidence of it being exploited, and gave US federal agencies until 21 Aug 2023 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 64%. 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
Ivanti 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.Ivanti Endpoint Manager Mobile (EPMM) 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 11.10.0.3 of EPMM), or not in use. CISA gave US government agencies until 21 Aug 2023 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.
