A vulnerability has been found in SourceCodester Employee Management System and classified as critical. This vulnerability affects unknown code of the file eloginwel.php. The manipulation of the argument id leads to sql injection. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. VDB-205834 is the identifier assigned to this vulnerability.

This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of ELOG Electronic Logbook 3.1.4-283534d. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of HTTP parameters. A crafted request can trigger the dereference of a null pointer. An attacker can leverage this vulnerability to create a denial-of-service condition. Was ZDI-CAN-10115.

A cross-site scripting (XSS) vulnerability in Electronic Logbook (ELOG) 3.1.4 allows remote attackers to inject arbitrary web script or HTML via a crafted SVG document to elogd.c.

A cross-site scripting (XSS) vulnerability in Electronic Logbook (ELOG) 3.1.4 allows remote attackers to inject arbitrary web script or HTML via the value parameter in a localization (loc) command to elogd.c.

ELOG 3.1.4-57bea22 and below can be used as an HTTP GET request proxy when unauthenticated remote attackers send crafted HTTP POST requests.

ELOG 3.1.4-57bea22 and below is affected by a denial of service vulnerability due to a NULL pointer dereference. A remote unauthenticated attacker can crash the ELOG server by sending a crafted HTTP GET request.

ELOG 3.1.4-57bea22 and below is affected by a denial of service vulnerability due to a use after free. A remote unauthenticated attacker can crash the ELOG server by sending multiple HTTP POST requests which causes the ELOG function retrieve_url() to use a freed variable.

ELOG 3.1.4-57bea22 and below is affected by an information disclosure vulnerability. A remote unauthenticated attacker can recover a user's password hash by sending a crafted HTTP POST request.

ELOG 3.1.4-57bea22 and below is affected by an information disclosure vulnerability. A remote unauthenticated attacker can access the server's configuration file by sending an HTTP GET request. Amongst the configuration data, the attacker may gain access to valid admin usernames and, in older versions of ELOG, passwords.

elog 3.1.1 allows remote attackers to post data as any username in the logbook.

Buffer overflow in Electronic Logbook (ELOG) before 2.7.1 has unknown impact and attack vectors, possibly related to elog.c.

The replace_inline_img function in elogd in Electronic Logbook (ELOG) before 2.7.1 allows remote attackers to cause a denial of service (infinite loop) via crafted logbook entries. NOTE: some of these details are obtained from third party information.

The show_elog_list function in elogd.c in elog 2.6.2 and earlier allows remote authenticated users to cause a denial of service (daemon crash) by attempting to access a logbook whose name begins with "global," which results in a NULL pointer dereference. NOTE: some of these details are obtained from third party information.

Multiple format string vulnerabilities in elogd.c in ELOG 2.6.2 and earlier allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via (1) an entry with an attachment whose name contains format string specifiers (el_submit function), and possibly other vectors in the (2) receive_config, (3) show_rss_feed, (4) show_elog_list, (5) show_logbook_node, and (6) server_loop functions.

Multiple cross-site scripting (XSS) vulnerabilities in elogd.c in ELOG 2.6.2 and earlier allow remote attackers to inject arbitrary HTML or web script via (1) the filename for downloading, which is not quoted in an error message by the send_file_direct function, and (2) the Type or Category values in a New entry, which is not properly handled in an error message by the submit_elog function.

Cross-site scripting (XSS) vulnerability in Elog 2.6.1 allows remote attackers to inject arbitrary web script or HTML by editing log entries in HTML mode.

Multiple stack-based buffer overflows in elogd.c in elog before 2.5.7 r1558-4 allow attackers to cause a denial of service (application crash) and possibly execute code via long "revision attributes".

Buffer overflow in elogd.c in elog before 2.5.7 r1558-4 allows attackers to execute code via unspecified variables, when writing to the log file.

The (1) elog.c and (2) elogd.c components in elog before 2.5.7 r1558-4 generate different responses depending on whether or not a username is valid, which allows remote attackers to determine valid usernames.

elog before 2.5.7 r1558-4 allows remote attackers to cause a denial of service (infinite redirection) via a request with the fail parameter set to 1, which redirects to the same request.
