01

What, why and how

Asseco InfoMedica is a comprehensive solution used to manage both administrative and medical tasks in the healthcare sector. A low privileged user is able to obtain encoded passwords of all other accounts (including main administrator) due to lack of granularity in access control.  Chained exploitation of this vulnerability and CVE-2025-8307 allows an attacker to escalate privileges. This vulnerability has been fixed in versions 4.50.1 and 5.38.0

What

Asseco InfoMedica is a comprehensive solution used to manage both administrative and medical tasks in the healthcare sector. A low privileged user is able to obtain encoded passwords of all other accounts (including main administrator) due to lack of granularity in access control.  Chained exploitation of this vulnerability and CVE-2025-8307 allows an attacker to escalate privileges. This vulnerability has been fixed in versions 4.50.1 and 5.38.0

Why

The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets.

How

An attacker operating through an adjacent network may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
an adjacent network → Insufficient Granularity of Access Control → cause the confidentiality, integrity or availability impact described by the vendor

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-1220

CWE-1220: Insufficient Granularity of Access Control. The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets.

CERT Polska otrzymał zgłoszenie o podatnościach w oprogramowaniu Asseco InfoMedica Plus i koordynował proces ujawniania informacji. Asseco InfoMedica to kompleksowe rozwiązanie służące do zarządzania zarówno zadaniami administracyjnymi, jak i medycznymi w sektorze ochrony zdrowia. Podatność CVE-2025-8306 : Z powodu braku odpowiedniej granulacji kontroli dostępu użytkownik o niskich uprawnieniach może uzyskać zakodowane hasła należące do innych użytkowników (w tym głównego administratora). Podatność CVE-2025-8307 : Hasła wszystkich użytkowników są przechowywane w bazie danych w formacie zakodowanym. Atakujący posiadający te hasła jest w stanie je odkodować, korzystając z algorytmu wbudowanego w część kliencką oprogramowania. Wykorzystanie obu podatności umożliwia atakującemu eskalację uprawnień. Obie podatności zostały naprawione w wersjach 4.50.1 oraz 5.38.0 .
