Vulnerabilidades

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> xfs: check for deleted cursors when revalidating two btrees<br /> <br /> The free space and inode btree repair functions will rebuild both btrees<br /> at the same time, after which it needs to evaluate both btrees to<br /> confirm that the corruptions are gone.<br /> <br /> However, Jiaming Zhang ran syzbot and produced a crash in the second<br /> xchk_allocbt call. His root-cause analysis is as follows (with minor<br /> corrections):<br /> <br /> In xrep_revalidate_allocbt(), xchk_allocbt() is called twice (first<br /> for BNOBT, second for CNTBT). The cause of this issue is that the<br /> first call nullified the cursor required by the second call.<br /> <br /> Let&amp;#39;s first enter xrep_revalidate_allocbt() via following call chain:<br /> <br /> xfs_file_ioctl() -&gt;<br /> xfs_ioc_scrubv_metadata() -&gt;<br /> xfs_scrub_metadata() -&gt;<br /> `sc-&gt;ops-&gt;repair_eval(sc)` -&gt;<br /> xrep_revalidate_allocbt()<br /> <br /> xchk_allocbt() is called twice in this function. In the first call:<br /> <br /> /* Note that sc-&gt;sm-&gt;sm_type is XFS_SCRUB_TYPE_BNOPT now */<br /> xchk_allocbt() -&gt;<br /> xchk_btree() -&gt;<br /> `bs-&gt;scrub_rec(bs, recp)` -&gt;<br /> xchk_allocbt_rec() -&gt;<br /> xchk_allocbt_xref() -&gt;<br /> xchk_allocbt_xref_other()<br /> <br /> since sm_type is XFS_SCRUB_TYPE_BNOBT, pur is set to &amp;sc-&gt;sa.cnt_cur.<br /> Kernel called xfs_alloc_get_rec() and returned -EFSCORRUPTED. Call<br /> chain:<br /> <br /> xfs_alloc_get_rec() -&gt;<br /> xfs_btree_get_rec() -&gt;<br /> xfs_btree_check_block() -&gt;<br /> (XFS_IS_CORRUPT || XFS_TEST_ERROR), the former is false and the latter<br /> is true, return -EFSCORRUPTED. This should be caused by<br /> ioctl$XFS_IOC_ERROR_INJECTION I guess.<br /> <br /> Back to xchk_allocbt_xref_other(), after receiving -EFSCORRUPTED from<br /> xfs_alloc_get_rec(), kernel called xchk_should_check_xref(). In this<br /> function, *curpp (points to sc-&gt;sa.cnt_cur) is nullified.<br /> <br /> Back to xrep_revalidate_allocbt(), since sc-&gt;sa.cnt_cur has been<br /> nullified, it then triggered null-ptr-deref via xchk_allocbt() (second<br /> call) -&gt; xchk_btree().<br /> <br /> So. The bnobt revalidation failed on a cross-reference attempt, so we<br /> deleted the cntbt cursor, and then crashed when we tried to revalidate<br /> the cntbt. Therefore, check for a null cntbt cursor before that<br /> revalidation, and mark the repair incomplete. Also we can ignore the<br /> second tree entirely if the first tree was rebuilt but is already<br /> corrupt.<br /> <br /> Apply the same fix to xrep_revalidate_iallocbt because it has the same<br /> problem.

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> xfs: check return value of xchk_scrub_create_subord<br /> <br /> Fix this function to return NULL instead of a mangled ENOMEM, then fix<br /> the callers to actually check for a null pointer and return ENOMEM.<br /> Most of the corrections here are for code merged between 6.2 and 6.10.

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> btrfs: fix reservation leak in some error paths when inserting inline extent<br /> <br /> If we fail to allocate a path or join a transaction, we return from<br /> __cow_file_range_inline() without freeing the reserved qgroup data,<br /> resulting in a leak. Fix this by ensuring we call btrfs_qgroup_free_data()<br /> in such cases.

*** Pendiente de traducción *** A zip slip vulnerability in the Admin import functionality of CTFd v3.8.1-18-gdb5a18c4 allows attackers to write arbitrary files outside the intended directories via supplying a crafted import.

*** Pendiente de traducción *** A Cross-Site Scripting (XSS) vulnerability exists in the web-based configuration interface of Zucchetti Axess access control devices, including XA4, X3/X3BIO, X4, X7, and XIO / i-door / i-door+. The vulnerability is caused by improper sanitization of user-supplied input in the dirBrowse parameter of the /file_manager.cgi endpoint.

*** Pendiente de traducción *** Glances is an open-source system cross-platform monitoring tool. Prior to version 4.5.2, the Glances REST API web server ships with a default CORS configuration that sets `allow_origins=["*"]` combined with `allow_credentials=True`. When both of these options are enabled together, Starlette&amp;#39;s `CORSMiddleware` reflects the requesting `Origin` header value in the `Access-Control-Allow-Origin` response header instead of returning the literal `*` wildcard. This effectively grants any website the ability to make credentialed cross-origin API requests to the Glances server, enabling cross-site data theft of system monitoring information, configuration secrets, and command line arguments from any user who has an active browser session with a Glances instance. Version 4.5.2 fixes the issue.

*** Pendiente de traducción *** The Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 4.0.3 via the &amp;#39;template&amp;#39; parameter in gallery shortcodes. This makes it possible for authenticated attackers, with Author-level access and above, to include and execute arbitrary .php files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included.

*** Pendiente de traducción *** Jenkins 2.554 and earlier, LTS 2.541.2 and earlier does not safely handle symbolic links during the extraction of .tar and .tar.gz archives, allowing crafted archives to write files to arbitrary locations on the filesystem, restricted only by file system access permissions of the user running Jenkins.<br /> This can be exploited to deploy malicious scripts or plugins on the controller by attackers with Item/Configure permission, or able to control agent processes.

*** Pendiente de traducción *** Jenkins 2.442 through 2.554 (both inclusive), LTS 2.426.3 through LTS 2.541.2 (both inclusive) performs origin validation of requests made through the CLI WebSocket endpoint by computing the expected origin for comparison using the Host or X-Forwarded-Host HTTP request headers, making it vulnerable to DNS rebinding attacks that allow bypassing origin validation.

*** Pendiente de traducción *** Jenkins LoadNinja Plugin 2.1 and earlier stores LoadNinja API keys unencrypted in job config.xml files on the Jenkins controller where they can be viewed by users with Item/Extended Read permission or access to the Jenkins controller file system.

*** Pendiente de traducción *** Jenkins LoadNinja Plugin 2.1 and earlier does not mask LoadNinja API keys displayed on the job configuration form, increasing the potential for attackers to observe and capture them.
