CVE Vulnerability Catalog

A vulnerability in Libevent before versions 2.1.13 and 2.2.2-alpha includes two HTTP parsing weaknesses in http.c. evhttp_decode_uri_internal decodes percent-encoded %00 bytes into literal NUL characters, which can cause path truncation and bypass validation. evhttp_header_is_valid_value also accepts obsolete line folding in header values containing CR or LF, allowing a proxy and libevent to interpret headers differently.

Libevent prior to 2.1.13 and 2.2.2-alpha has an incorrect integer conversion in event_tagging.c when evtag_unmarshal_header uses evtag_decode_int to decode an attacker-controlled uint32 payload length and returns it as a signed int. Values above INT_MAX become negative or truncated, and evtag_unmarshal_string can use the converted value in allocation sizing, producing a wrapped large allocation request and denial of service. This issue is fixed in versions 2.1.13 and 2.2.2-alpha.

Libevent prior to 2.1.13 and 2.2.2-alpha can read beyond a contiguous evbuffer region in event_tagging.c when decode_tag_internal requests at most five bytes from evbuffer_pullup but iterates using the full logical buffer length. A fragmented evbuffer containing a six-byte malformed tag can therefore advance past the pullup window and trigger an out-of-bounds read, which can crash a process that decodes attacker-controlled tagged RPC data. This issue is fixed in versions 2.1.13 and 2.2.2-alpha.

Libevent before versions 2.1.13 and 2.2.2-alpha inconsistently handles duplicate Transfer-Encoding headers, comma-separated values, and bare line feeds in chunked framing. This can lead to request desynchronization and request smuggling by an unauthenticated remote attacker when deployed behind a proxy.

Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has a use-after-free in buffer.c when evbuffer_add_buffer_reference processes an output buffer whose out_total_len is zero. evbuffer_free_all_chains frees the initial empty chain without resetting outbuf->first, outbuf->last, or outbuf->last_with_datap, and APPEND_CHAIN_MULTICAST subsequently dereferences the dangling chain pointer. A caller that can drive this buffer state can cause memory corruption or a process crash. This issue is fixed in versions 2.1.13 and 2.2.2-alpha.

Libevent before 2.2.2-alpha can dereference invalid list pointers in ws.c when evws_new_session enters its error path after evhttp_start_ws_ succeeds but bufferevent_enable_locking_ fails. This can cause a process crash.

Libevent before 2.1.13 and 2.2.2-alpha processes chunked HTTP trailers and merges them into request headers. An unauthenticated remote attacker can place security-sensitive fields in trailers, causing header smuggling, authorization bypass, proxy-header spoofing, or cache poisoning.

django CMS before 5.0.8 and 5.1.0 ignores request headers declared by plugins through get_vary_cache_on() when generating cache keys. This causes different users to receive content intended for others.

django CMS is an easy-to-use and developer-friendly enterprise content management system powered by Django. Prior to 5.0.8, the move_plugin endpoint in cms/admin/placeholderadmin.py accepts an attacker-controlled plugin_parent value without rejecting a plugin’s own identifier or a descendant identifier. A staff user with plugin-change permission under CMS_PERMISSION can create a parent_id cycle in the plugin tree. The _get_descendants_cte and _get_ancestors_cte queries in cms/models/pluginmodel.py have no cycle guard, so get_descendants() and later rendering, copy, or delete operations can recurse indefinitely or reach a database recursion limit, corrupting the tree and consuming request workers. This issue is fixed in versions 5.0.8.

Samly from version 0.3.0 has a vulnerability of insufficient verification of data authenticity, allowing an attacker to establish an authenticated session using a SAML response the service provider never requested. Validation does not compare the InResponseTo attribute with the AuthnRequest ID.

A vulnerability in dropbox samly allows an attacker to authenticate as the subject of a captured SAML assertion by resubmitting it. Samly does not enforce the single-use requirement because it never calls the duplicate-checking function.

In vsDesk v14.0101, an authenticated attacker with administrative privileges can bypass client-side file validation in the "Import via CSV" component due to lack of server-side validation. This allows uploading arbitrary files, potentially leading to Remote Code Execution (RCE) within the web application context.

In Kata Containers, configurations using genpolicy for Confidential Containers guest protection, a malicious host operator can exploit insufficient validation of CreateContainer mount and storage rules, allowing mounting arbitrary container-rootfs paths over sensitive host locations or provisioning arbitrary content.

A weakness has been identified in itsourcecode Hospital Management System 1.0. It affects an unknown part of the file /viewappointmentpending.php. Manipulation of the argument delid causes SQL injection. The attack can be carried out remotely, and the exploit is publicly available.

In Comfast CF-N1-S version 2.6.0.1, the function sub_44B438 in /cgi-bin/mbox-config?method=SET&section=ptest_ssid (SSID Configuration component) has a stack-based buffer overflow via the ssid argument.

CodeAstro Apartment Visitor Management System 1.0 is vulnerable to SQL injection in password-recovery.php via the email argument. The attack can be performed remotely, and the exploit is publicly available.

CodeAstro Apartment Visitor Management System 1.0 is vulnerable to SQL injection in /apartment-visitor/forgotpw.php via the secode argument. The attack can be performed remotely, and the exploit has been publicly disclosed.

This CVE has been rejected or withdrawn by its CVE Numbering Authority.

In Banks before version 2.4.5, DirectoryPromptRegistry.set() in src/banks/registries/directory.py interpolates attacker-controlled Prompt.name and Prompt.version values into a Path without canonicalization or containment validation. Relative traversal such as ../victim/foo and an absolute Prompt.name can escape or discard the configured registry root, while overwrite=True permits replacement of existing target files. The poisoned name is persisted in index.json and reconstructed by _load(), allowing the out-of-root path to survive later registry loads. An application that forwards request data into these fields can therefore write Prompt.raw bytes to attacker-chosen paths writable by the application process. This issue is fixed in version 2.4.5.

In the unstructured library (from 0.4.7 to 0.24.0), the url argument in partition, partition_html, and partition_md is fetched without host validation, allowing an attacker to access loopback addresses, internal HTTP services, or cloud metadata endpoints.
