Vulnerabilidades

*** Pendiente de traducción *** A flaw has been found in GL.iNet GL-MT3000 up to 4.4.5. The impacted element is the function logread.set_config of the file /usr/lib/oui-httpd/rpc/logread of the component Logread Lua RPC Plugin. This manipulation of the argument record_size causes command injection. The exploit has been published and may be used. The vendor was contacted early about this disclosure and confirmed the existence of the vulnerability.

*** Pendiente de traducción *** CTI-Transmute is affected by a server-side request forgery vulnerability in the evaluation report PDF-generation functionality.<br /> <br /> User-controlled CTI content, including conversion names, descriptions, and comments, is converted from Markdown to HTML and rendered as a PDF using WeasyPrint. Before the patch, the renderer used WeasyPrint’s default URL-fetching behavior without restricting the protocols or destinations that could be referenced by the generated HTML.<br /> <br /> An attacker able to supply content included in an evaluation report could inject crafted resource references using schemes such as http://, https://, or file://. When the report was rendered, CTI-Transmute could fetch these resources using the application server’s network connectivity and filesystem privileges.<br /> <br /> Successful exploitation could allow an attacker to:<br /> <br /> * access services available only from the CTI-Transmute server or its internal network;<br /> * probe internal hosts and service endpoints;<br /> * retrieve local files readable by the application process; and<br /> * expose fetched content through the generated PDF, depending on the referenced resource type and rendering context.<br /> <br /> <br /> The vulnerability is corrected by providing WeasyPrint with a restrictive URL fetcher that permits only self-contained data: URIs. The externally hosted Google Fonts stylesheet was also removed so that PDF generation performs no intentional network or filesystem fetches.

*** Pendiente de traducción *** CTI-Transmute contains an uncontrolled resource-consumption vulnerability in the unauthenticated /activity_timeline endpoint. The endpoint accepts a user-controlled days query parameter that was not restricted to a reasonable range.<br /> <br /> A remote, unauthenticated attacker could submit an excessively large value for this parameter, causing the application to retrieve and process activity data over an arbitrarily large period. This could consume excessive database, CPU, or memory resources, delay the processing of concurrent requests, or trigger an internal server error. Repeated requests could further degrade the availability of the CTI-Transmute website.<br /> <br /> The vulnerability is corrected by clamping the requested timeline range to a minimum of one day and a maximum of 1,095 days.

*** Pendiente de traducción *** CTI-Transmute contained a cross-site request forgery vulnerability in the administrative user deletion functionality. The /account/delete/ endpoint accepted HTTP GET requests for an operation that modified application state.<br /> <br /> An unauthenticated remote attacker could construct a malicious link or embed a request targeting this endpoint and induce an authenticated CTI-Transmute administrator to visit the attacker-controlled content. If the administrator had an active session, the browser would automatically include the administrator’s session credentials, causing the selected user account to be deleted without the administrator intentionally confirming the operation.<br /> <br /> Successful exploitation requires interaction from a currently authenticated administrator who has permission to delete users. The attacker does not need a CTI-Transmute account or administrative privileges because the forged request executes using the victim administrator’s session.<br /> <br /> The vulnerability could allow an attacker to delete arbitrary user accounts, resulting in unauthorized modification of application state and denial of access for affected users. Depending on whether administrators can delete other administrators or the final administrative account, exploitation could also disrupt administration of the CTI-Transmute instance.<br /> <br /> The patch resolves the issue by restricting the deletion endpoint to HTTP POST requests and submitting the deletion through a form containing a CSRF token.

*** Pendiente de traducción *** A flaw was found in SSSD. The sss_nss_protocol_parse_addr() function in the NSS responder does not validate the addrlen field against the remaining packet body size. A local attacker can exploit this via a crafted GETHOSTBYADDR request to the NSS responder socket, causing an out-of-bounds read and process crash, resulting in a denial of service.

*** Pendiente de traducción *** A vulnerability in Wapt Server before version 2.6.1.17813 allows a  remote unauthenticated attacker to bypass<br /> security restriction using a specially crafted packet and retrieve a valid<br /> session token for the targeted account.

*** Pendiente de traducción *** eParakstītājs 3.0 for Windows before version<br /> 1.10.0 retrieves and executes its automatic updates over a channel that is not<br /> authenticated or integrity-protected. On each launch the application fetches an<br /> update descriptor (XML) over TLS but accepts any TLS certificate (a permissive<br /> TrustManager and a HostnameVerifier that always returns true), does not verify<br /> any digital signature on the update descriptor, and does not verify the<br /> Authenticode signature or a checksum of the downloaded installer before running<br /> it. A man-in-the-middle attacker able to redirect www.eparaksts.lv can serve a<br /> crafted update descriptor pointing to an attacker-controlled executable, which<br /> the client downloads and executes, resulting in arbitrary code execution on the<br /> victim host.

*** Pendiente de traducción *** FlowIntel is affected by a stored cross-site scripting vulnerability through multiple user-controlled or administrator-controlled fields.<br /> <br /> Persisted values—including case titles, ticket identifiers, recurring-case information, user profile attributes, organisation names, and role names—were rendered inside DOM elements subsequently compiled by Vue. Although normal HTML escaping could neutralize direct HTML markup, it did not prevent an attacker from injecting Vue interpolation expressions using the configured [[ ... ]] delimiters.<br /> <br /> An authenticated attacker able to modify one of the affected fields could store a malicious Vue expression. When another user viewed an affected case, report, profile, recurring-case page, or navigation component, Vue could evaluate the injected expression in the context of the FlowIntel application.<br /> <br /> Successful exploitation could allow arbitrary JavaScript execution in the victim’s browser under the FlowIntel origin. This could expose information available to the victim, perform actions using the victim’s authenticated session, or modify application data within the victim’s privileges.<br /> <br /> The patch introduces a dedicated vue_escape filter that escapes HTML-sensitive characters and breaks Vue interpolation delimiters before the values are rendered. The filter is applied to the affected case, account, organisation, role, configuration, and navigation fields.

*** Pendiente de traducción *** Sharp and Toshiba Tec MFPs (multifunction printers) caches data internally when printing, and leave them uncleared. They may be accessed later by other users.

*** Pendiente de traducción *** Sharp and Toshiba Tec MFPs (multifunction printers) for a certain market have been shipped with the user authentication feature disabled in the initial configuration. When used with the initial configuration, the address book editing and a range of features related to Document Filing can be accessed without user authentication.<br /> Products intended for the Japanese market are not affected.

*** Pendiente de traducción *** Sharp and Toshiba Tec MFPs (multifunction printers) fail to properly authorize requests to directly access certain image data stored to the affected product.

*** Pendiente de traducción *** Network Scanner Tool and Network Scanner Tool Lite provided by Sharp Corporation, with the initial configuration, require no authentication and accept files unlimitedly. When the affected products are used with the initial configuration, anyone can connect to them without authentication and upload files unlimitedly. This may cause a denial-of-service (DoS) condition on the PC. Furthermore, if a malicious file is uploaded, a PC user may be tricked to execute the file to attack other entities from that PC.
