CVE-2023-35078
CVE-2023-35078 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 25 Jul 2023, and says ransomware gangs have used it.[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 11.10.0.2, 11.9.1.1 and 11.8.1.1 of endpoint_manager_mobile.
Description
CISA calls it an endpoint manager mobile authentication bypass in Ivanti Endpoint Manager Mobile (EPMM). In its words: “Ivanti Endpoint Manager Mobile (EPMM, previously branded MobileIron Core) contains an authentication bypass vulnerability that allows unauthenticated access to specific API paths. An attacker with access to these API paths can access personally identifiable information (PII) such as names, phone numbers, and other mobile device details for users on a vulnerable system. An attacker can also make other configuration changes including installing software and modifying security profiles on registered devices.”[1]
The underlying weakness is improper authentication (CWE-287), in MITRE’s list of common software weaknesses.[2]
It scores 9.8 out of 10 on the Common Vulnerability Scoring System, which rates it critical, scored by NVD using CVSS 3.1.[2]

Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 25 Jul 2023, within a day of it being made public. CISA lists a flaw only when it has reliable evidence of it being exploited, and gave US federal agencies until 15 Aug 2023 to fix it.[1] CISA says ransomware gangs have used it.
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 automatable: attackers can run it against many targets at once.
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 11.10.0.2, 11.9.1.1 and 11.8.1.1 of endpoint_manager_mobile), or not in use. CISA gave US government agencies until 15 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.
