HIGH 8.1

DescriptionCVE.org

TeamPass before 2.1.27.9 does not properly enforce item access control when requesting items.queries.php. It is then possible to copy any arbitrary item into a directory controlled by the attacker, edit any item within a read-only directory, delete an arbitrary item, delete the file attachments of an arbitrary item, copy the password of an arbitrary item to the copy/paste buffer, access the history of an arbitrary item, and edit attributes of an arbitrary directory. To exploit the vulnerability, an authenticated attacker must tamper with the requests sent directly, for example by changing the "item_id" parameter when invoking "copy_item" on items.queries.php.

AnalysisAI

TeamPass before 2.1.27.9 does not properly enforce item access control when requesting items.queries.php. Rated high severity (CVSS 8.1), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available.

Technical ContextAI

This vulnerability is classified as Improper Privilege Management (CWE-269), which allows attackers to escalate privileges to gain unauthorized elevated access. TeamPass before 2.1.27.9 does not properly enforce item access control when requesting items.queries.php. It is then possible to copy any arbitrary item into a directory controlled by the attacker, edit any item within a read-only directory, delete an arbitrary item, delete the file attachments of an arbitrary item, copy the password of an arbitrary item to the copy/paste buffer, access the history of an arbitrary item, and edit attributes of an arbitrary directory. To exploit the vulnerability, an authenticated attacker must tamper with the requests sent directly, for example by changing the "item_id" parameter when invoking "copy_item" on items.queries.php. Affected products include: Teampass. Version information: before 2.1.27.9.

RemediationAI

A vendor patch is available. Apply the latest security update as soon as possible. Apply principle of least privilege, validate privilege transitions, implement proper role separation.
