Description

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data when processing data passed via the (1) patient parameter to interface/main/finder/finder_navigation.php; (2) key parameter to interface/billing/get_claim_file.php; (3) formid or (4) formseq parameter to interface/orders/types.php; (5) eraname, (6) paydate, (7) post_to_date, (8) deposit_date, (9) debug, or (10) InsId parameter to interface/billing/sl_eob_process.php; (11) form_source, (12) form_paydate, (13) form_deposit_date, (14) form_amount, (15) form_name, (16) form_pid, (17) form_encounter, (18) form_date, or (19) form_to_date parameter to interface/billing/sl_eob_search.php; (20) codetype or (21) search_term parameter to interface/de_identification_forms/find_code_popup.php; (22) search_term parameter to interface/de_identification_forms/find_drug_popup.php; (23) search_term parameter to interface/de_identification_forms/find_immunization_popup.php; (24) id parameter to interface/forms/CAMOS/view.php; (25) id parameter to interface/forms/reviewofs/view.php; or (26) list_id parameter to library/custom_template/personalize.php. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
