Cognex In-Sight Explorer and In-Sight Camera Firmware expose a telnet-based service on port 23 to allow management operations such as firmware upgrades and device reboots, which require authentication. A user with protected privileges can successfully invoke the SetSystemConfig functionality to modify relevant device properties (such as network settings), contradicting the security model proposed in the user manual.

H3C devices running firmware version NX15V100R015 are vulnerable to unauthorized access due to insecure default credentials. The root user account has no password set, and the H3C user account uses the default password "admin," both stored in the /etc/shadow file. Attackers with network access can exploit these credentials to gain unauthorized root-level access to the device via the administrative interface or other network services, potentially leading to privilege escalation, information disclosure, or arbitrary code execution.

A command injection vulnerability in COMFAST CF-XR11 (firmware V2.7.2) exists in the multi_pppoe API, processed by the sub_423930 function in /usr/bin/webmgnt. The phy_interface parameter is not sanitized, allowing attackers to inject arbitrary commands via a POST request to /cgi-bin/mbox-config?method=SET&section=multi_pppoe. When the action parameter is set to "one_click_redial", the unsanitized phy_interface is used in a system() call, enabling execution of malicious commands. This can lead to unauthorized access to sensitive files, execution of arbitrary code, or full device compromise.

Dover Fueling Solutions ProGauge MagLink LX4 Devices fail to handle Unix time values beyond a certain point. An attacker can manually change the system time to exploit this limitation, potentially causing errors in authentication and leading to a denial-of-service condition.

An attacker with adjacent access, without authentication, can exploit this vulnerability to retrieve a hard-coded password embedded in publicly available software. This password can then be used to decrypt sensitive network traffic, affecting the Cognex device.

A local attacker with low privileges on the Windows system where the software is installed can exploit this vulnerability to corrupt sensitive data. A data folder is created with very weak privileges, allowing any user logged into the Windows system to modify its content.

LinkAce is a self-hosted archive to collect website links. Prior to 2.3.1, a Stored Cross-Site Scripting (XSS) vulnerability has been identified on the /system/audit page. The application fails to properly sanitize the username field before it is rendered in the audit log. An authenticated attacker can set a malicious JavaScript payload as their username. When an action performed by this user is recorded (e.g., generate or revoke an API token), the payload is stored in the database. The script is then executed in the browser of any user, particularly administrators, who views the /system/audit page. This vulnerability is fixed in 2.3.1.

In the Linux kernel, the following vulnerability has been resolved: PCI/ASPM: Disable ASPM on MFD function removal to avoid use-after-free Struct pcie_link_state->downstream is a pointer to the pci_dev of function 0. Previously we retained that pointer when removing function 0, and subsequent ASPM policy changes dereferenced it, resulting in a use-after-free warning from KASAN, e.g.: # echo 1 > /sys/bus/pci/devices/0000:03:00.0/remove # echo powersave > /sys/module/pcie_aspm/parameters/policy BUG: KASAN: slab-use-after-free in pcie_config_aspm_link+0x42d/0x500 Call Trace: kasan_report+0xae/0xe0 pcie_config_aspm_link+0x42d/0x500 pcie_aspm_set_policy+0x8e/0x1a0 param_attr_store+0x162/0x2c0 module_attr_store+0x3e/0x80 PCIe spec r6.0, sec 7.5.3.7, recommends that software program the same ASPM Control value in all functions of multi-function devices. Disable ASPM and free the pcie_link_state when any child function is removed so we can discard the dangling pcie_link_state->downstream pointer and maintain the same ASPM Control configuration for all functions.

In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix sysfs interface lifetime The current nilfs2 sysfs support has issues with the timing of creation and deletion of sysfs entries, potentially leading to null pointer dereferences, use-after-free, and lockdep warnings. Some of the sysfs attributes for nilfs2 per-filesystem instance refer to metadata file "cpfile", "sufile", or "dat", but nilfs_sysfs_create_device_group that creates those attributes is executed before the inodes for these metadata files are loaded, and nilfs_sysfs_delete_device_group which deletes these sysfs entries is called after releasing their metadata file inodes. Therefore, access to some of these sysfs attributes may occur outside of the lifetime of these metadata files, resulting in inode NULL pointer dereferences or use-after-free. In addition, the call to nilfs_sysfs_create_device_group() is made during the locking period of the semaphore "ns_sem" of nilfs object, so the shrinker call caused by the memory allocation for the sysfs entries, may derive lock dependencies "ns_sem" -> (shrinker) -> "locks acquired in nilfs_evict_inode()". Since nilfs2 may acquire "ns_sem" deep in the call stack holding other locks via its error handler __nilfs_error(), this causes lockdep to report circular locking. This is a false positive and no circular locking actually occurs as no inodes exist yet when nilfs_sysfs_create_device_group() is called. Fortunately, the lockdep warnings can be resolved by simply moving the call to nilfs_sysfs_create_device_group() out of "ns_sem". This fixes these sysfs issues by revising where the device's sysfs interface is created/deleted and keeping its lifetime within the lifetime of the metadata files above.

In the Linux kernel, the following vulnerability has been resolved: firewire: net: fix use after free in fwnet_finish_incoming_packet() The netif_rx() function frees the skb so we can't dereference it to save the skb->len.

In the Linux kernel, the following vulnerability has been resolved: scsi: ses: Handle enclosure with just a primary component gracefully This reverts commit 3fe97ff3d949 ("scsi: ses: Don't attach if enclosure has no components") and introduces proper handling of case where there are no detected secondary components, but primary component (enumerated in num_enclosures) does exist.

In the Linux kernel, the following vulnerability has been resolved: btrfs: don't check PageError in __extent_writepage __extent_writepage currenly sets PageError whenever any error happens, and the also checks for PageError to decide if to call error handling. This leads to very unclear responsibility for cleaning up on errors. In the VM and generic writeback helpers the basic idea is that once I/O is fired off all error handling responsibility is delegated to the end I/O handler. But if that end I/O handler sets the PageError bit, and the submitter checks it, the bit could in some cases leak into the submission context for fast enough I/O. Fix this by simply not checking PageError and just using the local ret variable to check for submission errors. This also fundamentally solves the long problem documented in a comment in __extent_writepage by never leaking the error bit into the submission context.

In the Linux kernel, the following vulnerability has been resolved: xsk: Fix xsk_diag use-after-free error during socket cleanup Fix a use-after-free error that is possible if the xsk_diag interface is used after the socket has been unbound from the device. This can happen either due to the socket being closed or the device disappearing. In the early days of AF_XDP, the way we tested that a socket was not bound to a device was to simply check if the netdevice pointer in the xsk socket structure was NULL. Later, a better system was introduced by having an explicit state variable in the xsk socket struct. For example, the state of a socket that is on the way to being closed and has been unbound from the device is XSK_UNBOUND. The commit in the Fixes tag below deleted the old way of signalling that a socket is unbound, setting dev to NULL. This in the belief that all code using the old way had been exterminated. That was unfortunately not true as the xsk diagnostics code was still using the old way and thus does not work as intended when a socket is going down. Fix this by introducing a test against the state variable. If the socket is in the state XSK_UNBOUND, simply abort the diagnostic's netlink operation.

In the Linux kernel, the following vulnerability has been resolved: drm/panfrost: Fix GEM handle creation ref-counting panfrost_gem_create_with_handle() previously returned a BO but with the only reference being from the handle, which user space could in theory guess and release, causing a use-after-free. Additionally if the call to panfrost_gem_mapping_get() in panfrost_ioctl_create_bo() failed then a(nother) reference on the BO was dropped. The _create_with_handle() is a problematic pattern, so ditch it and instead create the handle in panfrost_ioctl_create_bo(). If the call to panfrost_gem_mapping_get() fails then this means that user space has indeed gone behind our back and freed the handle. In which case just return an error code.

In the Linux kernel, the following vulnerability has been resolved: ACPICA: Fix error code path in acpi_ds_call_control_method() A use-after-free in acpi_ps_parse_aml() after a failing invocaion of acpi_ds_call_control_method() is reported by KASAN [1] and code inspection reveals that next_walk_state pushed to the thread by acpi_ds_create_walk_state() is freed on errors, but it is not popped from the thread beforehand. Thus acpi_ds_get_current_walk_state() called by acpi_ps_parse_aml() subsequently returns it as the new walk state which is incorrect. To address this, make acpi_ds_call_control_method() call acpi_ds_pop_walk_state() to pop next_walk_state from the thread before returning an error.
